Queens University faculty member Jordan Poppenk will be giving a talk in the Suedfeld Lounge on June 26th at 1:00pm. Details below:
Title: Distinguishing between anterior and posterior hip
pocampal contributions to
our traits and abilities
Abstract: Considerable investigation and theor
etical development has sought to
distinguish the mnemonic role played
by the hippocampus from that played
by other neuroanatomical structure
s in the medial temporal lobes. Now\,
mounting evidence suggests that
medial temporal lobe contributions to
human memory may be further dist
inguished based on distinctions within the
hippocampus itself. In part
icular\, recent evidence suggests that anterior
and posterior extents
of the structure subserve human memory in different
ways. In this talk
\, I will address the questions: a) in what ways is the
hippocampus fu
nctionally heterogeneous along its long (anterior to
posterior) axis\;
and b) how is such functional heterogeneity possible when
the interna
l circuitry of the hippocampus is nearly identical within its
anterior
and posterior extents? To address these questions\, I will
synthesize
volumetric\, connectivity\, lesion\, and functional results\, and
pre
sent evidence of distinctive anterior and posterior hippocampal
contri
butions to a wide range of traits and abilities\, from memory
retentio
n to emotional processing and personality.
