17.10-17.20 Break

Prof Sara Aton

17.20-18:00 Professor Sara Aton, University of Michigan:
How sleep loss disrupts hippocampal memory mechanisms 

Dr. Sara Aton received her PhD from Washington University in St .Louis, and carried out postdoctoral work at the University of Pennsylvania with Dr. Marcos Frank. Her laboratory at the University of Michigan, established in 2012, has investigated two sleep-dependent phenomena - consolidation of fear memories in the mouse hippocampus, and consolidation of experience-dependent plasticity in mouse primary visual cortex. Work from her lab, combining in vivo electrophysiology with optogenetic and pharmacogenetic manipulations of brain circuits, has established the vital role for sleep-associated network oscillations in driving both processes. Current studies being carried out in the Aton lab are characterizing how learning experiences and subsequent sleep affect basic biochemical processes in specific neuronal cell types, excitatory/inhibitory balance, and the activity and plasticity of experience-activated  (i.e. engram) neurons.  

Prof Ruth Benca

18:00-18:40 Professor Ruth Benca, University of California, Irvine:
Sleep and Psychiatry

Dr. Ruth Benca is Professor and Chair, Department of Psychiatry and Human Behavior at the University of California, Irvine.  She received her AB at Harvard and her MD and PhD degrees from the University of Chicago. She has been a faculty member at the University of Chicago and the University of Wisconsin-Madison, where she was Associate Chair of the Psychiatry Department and Director of the UW Center for Sleep Medicine and Sleep Research. She moved to UC Irvine in 2016, where she has established a sleep medicine center providing clinical care for sleep disorders as well as promoting translational research. Her research focuses on the interface between sleep and psychiatric disorders across the lifespan, and the role of sleep and sleep disorders on Alzheimer’s disease. She has served as principal investigator for studies funded by agencies including the NIH and the DOD.  Her work has spanned basic research in animal models to clinical research and clinical trials. She has authored over 150 articles, reviews and book chapters.

European Sleep Science Award 2020

Dear Colleagues,  

It was my pleasure to present Dr. Tarja Porkka-Heiskanen – a sleep scientist, teacher, debater, and influencer in sleep medicine – with the European Sleep Science Award 2020 during the Welcome and Opening of the Virtual Edition of our 25th Congress of the European Sleep Research Society (22 Sept 2020). 

Dr. Porkka-Heiskanen received her medical degree in 1983 and her doctoral degree in 1990 from the University of Helsinki. She performed her postdoctoral studies during the 1990’s in the USA at Northwestern University and Harvard Medical school – spending two years at both. 

A central revelation by Dr. Porkka-Heiskanen related to homeostatic regulation of sleep, where she identified adenosine as a key regulatory molecule during her postdoctoral research in the lab of Robert W. McCarley. This finding was published in Science in 1997 and since then, it has been one of the central reports in sleep medicine that paved the path for many other roads in modern sleep research. 

Her interest in sleep research has been exceptionally wide; centered around the basic physiological mechanisms of sleep regulation, it has also extended to broader developmental dimensions –from early development to ageing, as well as to specific, gender-related aspects. She also pioneered studies on the consequences of sleep deprivation on the immune system. In 2018, Dr. PorkkaHeiskanen was awarded The Pisa Sleep Award

She has also had central roles in many international activities, including membership in the ESRS Education and Research Committees and Board, chairing the EU Committee and establishing the ESRS Forum for Women. She has acted on the Editorial Boards of several respected international sleep journals, including the Journal of Sleep Research. 

Regarding her contribution towards scientific collaboration, she has coordinated several sleepcentered international consortia and is particularly active in postgraduate education, both nationally and internationally. She established the notable Sleep School at the University of Helsinki, which recently turned into a combination of digital education and hands-on practice – all thanks to Tarja’s efforts. More recently, she pioneered future educational activity at ESRS by establishing the webbased education on basic sleep research, “eLessons”.

Tarja is still active at the University of Helsinki. She is one of our PIs for the SleepWell Research program – the first internationally evaluated research program oriented on sleep medicine at the faculty level in Finland.

As a colleague, she has been exceptionally supportive and innovative. At the same time, she is uncompromising in scientific integrity, logical thinking and scientific reasoning. 

Beyond scientific activities, as some of you might know, she is an excellent dancer; she loves her garden; she is an excellent writer (and could have accomplished a career as a writer if she had wished to do so) – and, most importantly she has an unfailing sense of humor.

Again, it was my great honor – and pleasure – to introduce Dr. Tarja Porkka-Heiskanen as the recipient of the European Sleep Science Award 2020. 

Thank you for your contributions towards the field of sleep science, the ESRS and your scientific collaboration and support of colleagues and young scientists.

ENCORE in Depression:
Synaptic Homeostasis, Plasticity, and Sleep Integrate Rapid Antidepressant Effects

Laboratory of Neurotherapeutics, Drug Research Program, Division of Pharmacology and Pharmacotherapy, Faculty of Pharmacy, & SleepWell Research Program, Faculty of Medicine, University of Helsinki, Finland

Dr. Rantamäki and his team investigates neurobiological mechanisms underlying rapid antidepressant effects. In this seminar he will present their latest findings and recently formulated hypothesis called encoding, consolidation and renormalization in depression (ENCORE-D) that aims explaining rapid (and sustained) antidepressant effects of ketamine and related drugs beyond conventional pharmacology. The hypothesis suggests that rapid and sustained antidepressant effects rely on intrinsic homeostatic mechanisms evoked as a response to the acute pharmacological or physiologic effects (e.g. prominent synaptic potentiation) triggered by the treatment. The hypothesis incorporates elements from the synaptic homeostasis hypothesis (SHY) of sleep and suggests that the fundamental mechanisms of synaptic plasticity and sleep, particularly the homeostatic emergence of slow-wave EEG activity and the renormalization of synaptic strength, are at the center of sustaining antidepressant effects. ENCORE-D provides an interesting mechanistic framework for studying and developing rapid-acting antidepressants.

Tiedekulma STA­GE

Ihmeellinen uni

Uni on terveydelle elintärkeää. Se luo perustan niin ihmisten kuin eläinten hyvinvoinnille ja oppimiselle. Unen puutteessa mieliala kärsii, suorituskyky laskee ja pidemmän päälle fysiologisista vaikutuksista voi seurata terveysongelmia. Mutta mitä uni oikeastaan on ja miten sitä tutkitaan? Miten eläinten uni liittyy ihmisten uneen?

Helsingin yliopiston unitutkijat tarkastelevat Tiedekulmassa unta ja nukkumista eri näkökulmista. Tapahtuman juontaa Reetta Räty.

Tapahtuma on osa Tiedekulman Helsinki Health Weekiä, joka vie sinut elämäntieteiden huippuosaamisen äärelle. Osallistu tapahtumaan paikan päällä, seuraa livestriimiä tai katso tallenne! Klikkaa itsesi mukaan tapahtumaan myös Facebookissa.

Puhujat

Tiedekulma Ihmeellinen uni puhujat

Laura Hänninen (@laurathanninen) on kliininen opettaja Eläinten hyvinvoinnin tutkimuskeskuksessa eläinlääketieteellisessä tiedekunnassa ja on eläinten hyvinvointiin ja käyttäytymiseen hurahtanut eläinlääkäri. “Eläinten käyttäytyminen on portti niiden mieleen, mahdollisuus saada, edes hämärästi, käsitys, mitä ne ajattelevat, mistä pitävät, mitä tuntevat”, hän sanoo. Vinkki terveyden ja hyvinvoinnin edistämiseen: “Riittävä uni! Nukun paljon, ja mielelläni.”

Tutkijatohtori Liisa Kuula (@LiisaKuula) on kognitiotieteilijä ja unitutkija Helsingin yliopistossa. Hän tutkii ihmisten nukkumista ja siihen liittyviä erilaisia ilmiöitä. Liisasta on merkillistä, että lähes kolmannes elämästämme kuluu unessa. Uni on edelleen tutkimuksellekin mysteeri, ja sen mahdista paljastuu koko ajan uutta tietoa. Tutkimusryhmänsä kanssa Liisa pyrkii löytämään syitä unen määrän, laadun ja ajoituksen vaihtelulle ja selvittämään, miten uneen voi vaikuttaa. Vinkki terveyden ja hyvinvoinnin edistämiseen: “Omaa uniterveyttään voi parantaa menemällä viikonloppuisin vartin aikaisemmin nukkumaan kuin arkisin – helppo ja halpa arvostuksen osoitus itselle.”

Tomi Rantamäki (@TomiRantamki) on molekulaarisen farmakologian apulaisprofessori farmasian tiedekunnassa ja mukana lääketieteellisen tiedekunnan SleepWell-tutkimusohjelmassa. Hän johtaa tutkimusryhmää, joka selvittää masennuslääkkeiden vaikutusten mekanismeja. Perinteisestä farmakologisesta ajattelusta poiketen tutkimusryhmä uskoo parhaiden vastausten löytyvän aivoista itsestään – siitä, miten aivot reagoivat hoitoihin. Erityisen kiehtovana Tomi pitää sitä, miten uni ja sen mekanismit liittyvät masennushoitojen toimintaan. Vinkki terveyden ja hyvinvoinnin edistämiseen: “Ole aktiivinen ja osallistuva, ja ennen kaikkea armollinen itsellesi.”

Henna-Kaisa Wigren on yliopistotutkija SleepWell-tutkimusohjelmassa ja unitutkimusryhmän nuorempi ryhmänjohtaja. Henna-Kaisa väittää, että aivojen toimintaa on mahdotonta ymmärtää tutkimalla pelkästään valvetta. Sen sijaan pitää ymmärtää, miksi vireystilat vuorottelevat ja miten aivojen tiedonkäsittely muuttuu unen ja valveen välillä. Erityisesti häntä kiinnostaa, miksi uni on elintärkeää ja miksi unta tai unenkaltaista tilaa esiintyy kaikilla lajeilla. Vinkki terveyden ja hyvinvoinnin edistämiseen: “Kun tekee valveilla ollessaan intensiivisesti aivoja haastavia asioita, jotka tuottavat mielihyvää, tulee samalla vahvistaneeksi luonnollisen unipaineen kertymistä ja silloin uni on yöllä syvempää, pidempää ja palauttavampaa.”
