Choroid Plexus Where? Remember ependymal cells
(Glial) And what do they synthesize and secrete?

This stuff is formed by which cells? And it is
made of ? And forms part of which barrier?
Corpora Amylacea

What is present in this structure that makes this
a ganglion?
Ganglion

Remember Meissners and Auerbachs Plexi in the
GI Submucosa v Muscularis externa

Between 2 muscle layers therefore an Auerbachs.
Wheres Meissners

Nerve cell bodies in this HP of Meissners so it
is a ganglion

22Encephalitis
- Encephalitis is typically caused by viral
infections of the brain - Herpes simplex
- Cytomegalovirus
- Polio virus (more often affect spinal cord rather
than brain) - Classic hallmark is presence of perivascular
cuffs of lymphocytes (aggregates of lymphocytes
surrounding the small arteries and arterioles)
23Encephalitis
- Lymphocytes surround small blood vessels, called
lymphocyte cuffing
24Encephalitis
- Neuronophagia (arrows) refers to dead or dying
neurons surrounded by clusters of microglial
cells (which are normally indistinct in brain
tissue)
25The beginnings of lobotomy can be traced back to
1847 in America. An explosion drove an iron bar
through the front part of the head of an Irish
mine worker named Phineas Gage, who actually
survived. The doctors were interested to discover
that not only did he survive, his personality was
completely changed. In 1890, this inspired Dr.
Gottlieb Burckhardt, superintendent of a German
psychiatric hospital, to drill holes into the
heads of six severely agitated patients and
extract material from the frontal lobe.
