Neuroanatomy I: Structures

Marc Norman, Ph.D., ABPPAmanda Gooding, Ph.D., ABPP

Department of PsychiatryNeuropsychology Clinical Training Seminar (NCTS)

About NCTS

• Year-long didactic course for trainees• Topics include: neuroanatomy, neuropathology, clinical syndromes,

psychometrics, data interpretation, neuroimaging (MRI, MRA, SPECT, PET), behavioral neurology, and professional and practice issues (e.g., case reviews, ABCN-style fact finding exercises, etc.).

• Typically, NCTS is offered only to UCSD clinical trainees; however, we are interested in potentially expanding our didactic series to a broader audience.– In particular, we are striving to promote equity, diversity, and inclusion in training,

recruitment, and sponsorship of emerging scientist practitioners.• This will be a 3-week trial period to determine feasibility. We will re-evaluate

whether this is ongoing after that time.

Neostriatum or striatum

• Caudate + Putamen– Receives all input to BG– Most cortical input is excitatory • (glutamate)

– Output is GABA
