A brain after suffering the effects of Alzheimers

normal brain (left), schizophrenic brain (right), MRI
Neuroanatomical abnormalities associated with schizophrenia include enlargement of the ventricles and diffuse cortical atrophy. Schizophrenia is associated with elevated dopamine, serotonin, norepinephrine and decreased gamma-aminobutyric acid.

Images caption: (a) Transverse graphic representation shows multiple cystic masses in the choroid plexus glomi (arrows). Most CPCs are actually degenerative xanthogranulomas.

(b) Transverse contrast-enhanced T1-weighted MR image in a healthy 52-year-old man shows bilateral CPCs with peripheral and nodular enhancement (arrows).
CHOROID PLEXUS CYSTS
Choroid plexus cysts (CPCs) are nonneoplastic epithelial-lined cysts of the choroid plexus. They are the most common of all intracranial neuroepithelial cysts, occurring in up to 50% of autopsy cases. Most are bilateral and located in the lateral ventricular atria. The third ventricle is a rare but reported location (1). Most CPCs are asymptomatic and are found incidentally, typically in neonates and older adults. Symptomatic lesions are rare since the atria typically enlarge to accommodate the cyst

Intraventricular hemorrhage with subarachnoid extension, ventral surface of brain.
Ventricular blood emanating through foramina of Lushcke and Magendie to cover the posterior cerebellum at the base of the brain. As described initially by Thomas Willis (of circle of Willis fame), intraventricular hemorrhage is often first encountered by the pathologist as grummous blood encircling the base of the brain.

Memories are Held in Specific Brain Cells
Our fond or fearful memories — that first kiss or a bump in the night — leave memory traces that we may conjure up in the remembrance of things past, complete with time, place and all the sensations of the experience. Neuroscientists call these traces memory engrams.
But are engrams conceptual, or are they a physical network of neurons in the brain? In a new MIT study, researchers used optogenetics to show that memories really do reside in very specific brain cells, and that simply activating a tiny fraction of brain cells can recall an entire memory — explaining, for example, how Marcel Proust could recapitulate his childhood from the aroma of a once-beloved madeleine cookie.

I see Dr. Crane has rejoined us online.
Blackgate certainly has interesting methods for therapy and rehabilitation.

Anonymous asked: What do your other personalities think of the Joker? Would you know? They definitely weren't around when you were treating him, but they have the same knowledge of him as you and all, right?
I…don’t know. I don’t know what they see. What they do. How they even feel. Harley wasn’t as fully realized as she is now, neither was the third,...
