https://www.biorxiv.org/content/10.1101/2021.11.26.468907 A null hypothesis for the current model is no evidence of balanced homeostatic systems in the brain. This means all cortical, limbic, basal, etc circuits must have an equivalent partner in the brainstem and cerebellum. My prior assumption was that was that place and direction equivalents were functions of the cerebellar DCN’s. This study […]

I recently got interested in this topic because it seems like the most acute of the “mental health” conditions that we need to address before we can start moving toward a healthier brain model. My general understanding of psychosis is that it’s an artifact of hippocampal complex function, particularly either dentate gyrus or the CA2<->CA3

One of my ongoing experiments is testing the parameters of tDCS. About three months ago I came across a montage which showed a noticeable effect on my EEG recordings. The montage is a bit complicated compared to most, however in all of my testing it’s the only one that’s showed efficacy in test pools greater

Towards optimization of oscillatory stimulation during sleep This study is fascinating but limited because they only used older participants who likely have decreased or no slow wave generation at all. I’m wondering if similar work has been done on younger patients. What’s interesting is that it appears that the primary etiology of most neurogeneration isn’t

Fear learning induces α7-nicotinic acetylcholine receptor-mediated astrocytic responsiveness that is required for memory persistence Updating after I read it, but looking at the supplements, it’s another behavior is an artifact of astrocytes not neurons support. Task dynamics define the contextual emergence of human corralling behaviors A reminder that behavior is behavior, human or otherwise. Cross-Task

Metaplastic Reinforcement of Long-Term Potentiation in Hippocampal Area CA2 by Cholinergic Receptor Activation So this hits for a couple of different reasons. First, I think it makes an argument that anxiolytic drugs work by essentially turning off the ability to process social information (“learn”). This suggests that such bidirectional synaptic modifications triggered by the dynamic

Feasibility evaluation of transtympanic laser stimulation of the cochlea from the outer ear Uh… I think I’m going to start wearing headphones all the time now. Kidding, but it does make me wonder what kind of range something like this would have if we used fNIRS levels of power. I wonder how “close” enough it

Hey anyone reading, just wanted to check in because I have quite a few open threads right now and wanted to give a general status update. I’ve been super busy over the last week and likely to be so until hopefully as soon as early December which means I have a lot less time to
