WhatsApp's unusual badge behaviour is quite good for most people (not tech savvy, completionist, or OCD).

I've you've ever looked at a normal person's homescreen I'm sure you remember how you felt as you gazed upon their 5-digit red app badges. Gmail 31,415. Messenger 652. YouTube 927. These are meaningless and to them impossible to maintain. They cope via Notification Center, where their inaction is equivalent to us clearing.

cf le vin : " 'l'expérience' tend à nous enseigner que la qualité se paye" -> "un même vin est mieux évalué lorsque son prix est élevé -> appréciation du #cortex orbitofrontal médian liée à l'émergence de ressenti plaisants." (rien à voir avec le goût donc)

"[...] quel que soit le prix du vin, la réponse des aires cérébrales impliquées dans le traitement des informations sensorielles gustative est identique."

#cortex préfontal droit = attention/prise de décision/apprentissage/règles symbolique/inhibition comportementale/navigation spatiale.

"le désir de #jouer conduit à un épaississement du cortex préfontal dorso-latéral" = sollicitation du système de récompense -> impulsivité comportementale/risque addictions -> usage pathologique.

#adolescence = pic de maturation majeure aires corticales préfontales = vulnérabilité acquisition/développement émotion/social/cognitif

Continued thread

"Chez l'adolescent et le jeune adulte, [le] développement [du Q.I.] est associé à un affinement progressif du #cortex pour nombre de zones, [...] préfontales, que les études relatives à l'influence des jeux-vidéos ont décrites comme plus épaisses." voire -> dépendance -> "la surépaisseur corticale observée chez les gamers avec une diminution du QI."

simplisme des notions neurologiques utilisées par les lobbies économiques.

New #introduction for neuromatch.social 🙂

My group investigates and defines cell types and neural circuits of the #thalamus, #hippocampus, and #cortex that contribute to spatial #memory processes.
These processes break down in #Alzheimer's disease. To understand the causes/triggers of #neurodegeneration, we study early-stage #Tau #pathology in the human #brain and in mouse models.

I previously defined various types of retinal ganglion cells using ex vivo #patchclamp recordings during my PhD in #Basel, before moving to #Oxford to work on #GABAergic #neurons of the #hippocampus, followed by the #medialseptum. My favourite technique is in vivo #extracellular recordings and #juxtacellular labelling as it enables identification of single #cells based on their firing patterns, #axon terminal distribution, and #neurochemical profile.

As an #experimentalist, my expertise is primarily in vivo #neurophysiology and #neuroanatomy. I am also interested in #consciousness, the origins of #memory, and regulation of #neuronal activity and #behaviour by #neuropeptides.

#introduction
I am neuroscientist and engineer. Our lab at Johns Hopkins University BME is interested in how the brain computes information about the world and how this representation is shaped by sensory experience from early development up until old age. We focus on the auditory system and use in vitro and in vivo optical and electrophysiological methods, behavioral approaches, etc.
