Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Psilocybin reduces fear memory and restores neuroplasticity in the hippocampus and medial prefrontal cortex

 

Of course your competent? doctor ignored all the previous positive research on psilocybin for stroke! Over a decade of incompetence!

Psilocybin reduces fear memory and restores neuroplasticity in the hippocampus and medial prefrontal cortex


Abstract

Background:

 Posttraumatic stress disorder (PTSD) and major depressive disorder are often comorbid in humans. Psilocybin reportedly has beneficial therapeutic effects on depression, possibly by promoting neuroplasticity. PTSD is associated with the dysregulation of neuroplasticity in the hippocampus and medial prefrontal cortex (mPFC). We hypothesized that psilocybin might reduce fear memory by promoting neuroplasticity in the hippocampus and mPFC.
 We investigated the effects of psilocybin on fear memory and explored its underlying mechanisms. We generated a mouse model of PTSD via auditory-cued fear conditioning and treated the mice with either vehicle or psilocybin (2.5 mg/kg, intraperitoneal) on day 0. Fear memory was assessed by the percentage of freezing time in response to conditioned stimuli. Fear memory tests were conducted on days 1, 6, and 7, after which the mice were sacrificed. To investigate the role of neuroplasticity in mediating the effects of psilocybin on fear memory, we assessed structural neuroplasticity and neuroplasticity-associated marker protein levels in the hippocampus and mPFC 7 days after a single dose of psilocybin.

Results:

Psilocybin reduced the cue-induced fear response on days 1, 6, and 7. Psilocybin ameliorated the fear conditioning-induced decreases in neuroplasticity in the hippocampus and mPFC. Through Golgi-Cox staining, Western blotting, and immunofluorescence staining, we found that psilocybin increased dendritic branches and spine density, upregulated GluR1 and synapsin-1, enhanced brain-derived neurotrophic factor and mammalian target of rapamycin signaling, and promoted neurogenesis.

Conclusions:

A single dose of psilocybin reduces both the rapid and sustained fear memory in mice, at least in part by restoring neuroplasticity in the hippocampus and mPFC. These findings indicate that psilocybin has significant potential for use in the treatment of PTSD and other mental disorders characterized by fear memory.
