"This book appealed to my split personality by
satisfying both my scientific and literary brain and
felt like I was reading two books in one." A generous, thoughtful review (pp. 61-63) by #Dr. Emma Durrant, clinical #scientist in #neurophysiology, of my #memoir, written with #UCSF#neurologist Dr. Bruce Miller. Here is a link to the entire volume published in The Journal of the Association of Neurophysiological Scientists.
Does someone here know of any master-level courses in Cognitive (Neuro)Physiology within "Human Neuroscience" programs? If yes, I'd appreciate a link to i.e. course description, syllabus, etc. - I'm trying to figure out how such a course would fit within a program that currently has no dedicated physiology course as part of the curriculum. Thanks in advance! 🧠✨ #cognitivescience#CognitiveNeuroscience#neuroscience#neurophysiology
I was told by a neighbour this morning that I am "the right kind of immigrant".
When asked to explain he said that I work and pay taxes. He didn't also say that I'm ok because I'm white but I wonder how the conversation would have gone if I had a different skin colour.
Am I reassured that because i am "the right kind of immigrant" everything will now be fine in the Netherlands after a quarter of the people who live around me just voted for a fascist, when the new speaker in our parliament is a conspiracy theorist as well as a fascist, and when most of the rest of the country appears to think that this is just fine ? No I am not.
I have more in common with asylum seekers and any other immigrants than I do with fascists or with unthinking voters for fascists. #pvvisfascism #RefugeesAreWelcomeHere
@itzpaquet@hembrow You can’t train a brain hypersensitive to detecting threats, scheming and doublecrossing from it’s environment to not be more sensitive to that, even if you want to.
Polticial alignments cannot be changed as readily as we’d like.
We are editing a collection in #JNeurophysiol about the Functional Logic of #NeuralCircuits!
See details below, in the link and flyer; and send us your research, reviews, or opinion papers! The deadline is Sep 1st, 2024.
I am pleased to announce that we have finally come to the conclusion of a work begun a long time ago.
It is a historical review of human motor invariants in action execution. The article contains more than 350 references and is followed by 7 comments from esteemed colleagues (+ our response).
In essence, it contains all the context and background to understand why we believe that action perception is fundamentally constrained by the way we plan and produce actions.
I am pleased to link here the second paper in our series investigating the connectivity between the ventral premotor cortex and the primary motor cortex by means of transcranial magnetic stimulation.
"The ventral premotor cortex (PMv) and primary motor cortex (M1) represent critical nodes of a parietofrontal network involved in grasping actions, such as power and precision grip. Here, we investigated how the functional PMv-M1 connectivity drives the dissociation between these two actions. We applied a PMv-M1 cortico-cortical paired associative stimulation (cc-PAS) protocol, stimulating M1 in both postero-anterior (PA) and antero-posterior (AP) directions, in order to induce long-term changes in the activity of different neuronal populations within M1. We evaluated the motor-evoked potential (MEP) amplitude, MEP latency and cortical silent period, in both PA and AP, during the isometric execution of precision and power grip, before and after the PMv-M1 cc-PAS. The repeated activation of the PMv-M1 cortico-cortical network with PA orientation over M1 did not change MEP amplitude or cortical silent period duration during both actions. In contrast, the PMv-M1 cc-PAS stimulation of M1 with an AP direction led to a specific modulation of precision grip motor drive. In particular, MEPs tested with AP stimulation showed a selective increase of corticospinal excitability during precision grip. These findings suggest that the more superficial M1 neuronal populations recruited by the PMv input are involved preferentially in the execution of precision grip actions."
In addition to the (VERY!)interesting implications of this study, I would like to point out that TMS-evoked movements are a very elegant way to non-invasively extract multijoint (hand) motor co-ordination patterns at rest or during action preparation.
...while others have focused on various research questions, such as the impact that long-term training (e.g., musicians), neurological disorders (e.g., stroke) or action observation have on (evoked-)hand coordination patterns.
On this latter topic we've contributed the following pieces:
