Subject: Reminder: Hebb Lecture - Dr. Mark Baxter - McGill University

Dear All,

A reminder that our next Hebb Speaker is Dr. Mark Baxter (Mount Sinai School of Medicine) . Dr. Baxter's research focuses on the neural mechanisms of executive function and the way in which these mechanisms fail in aging and neuropsychiatric disorders. He works with animals models (rats and monkeys) with a particular emphasis on the fronto-temporal circuitry.

The lecture will take place on Friday 25th March, 2011, at 3:30pm in Stewart Biology Building, Room S1/3 (PLEASE NOTE ROOM CHANGE). Title and abstract are below.

Title:
A cholinergic explanation of dense amnesia

Abstract:
Acetylcholine is the neuromodulator most closely identified with memory function, primarily because the loss of acetylcholine in patients with Alzheimer's disease tracks the severity of their cognitive impairment.  I will review research from my laboratory (and others) that places important constraints on a cholinergic explanation of memory impairment, based on experimental studies in animals in which the cognitive effects of selective ablation of cholinergic neurons can be studied. Specifically, loss of basal forebrain cholinergic neurons cannot account for severe, global memory impairments in neurodegenerative diseases.  However, we have recently identified a role for acetylcholine in recovery of function after structural damage to brain circuits important for episodic memory.  These recent findings suggest that the involvement of cholinergic deficits in dementia may be related to impairment of a process that would normally allow for some preservation of memory function in the face of structural damage, rather than a direct involvement of acetylcholine in supporting memory per se.

The lecture will be followed by a cheese and wine on the 8th floor lobby of the Psychology Department, in Stewart Biology Building.

Cheers,
Yogita
