312. Emerging Roles for Somatostatin-Containing
Cortical Interneurons: Novel Insights From
Transgenic Mice — CME
Mon. 8:30 AM - 11:00 AM — 145B
Chair: A. AGMON
Somatostatin-containing (SOM), inhibitory cortical
interneurons have long been thought to play second fiddle
to the better-known “fast spiking” (FS) interneurons. Studies
using SOM-specific mouse lines are now challenging this
perception, revealing how the unique properties of SOM
interneurons, such as their facilitating inputs, distal dendritic
targeting and sensitivity to neuromodulators, allow them
to sculpt cortical activity in a manner distinct from, but
complementary to, FS interneurons.

313. New Insights on Diverse Neural Mechanisms
Underlying Alcohol Dependence/Addiction — CME
Mon. 8:30 AM - 11:00 AM — 202B
Chair: C. CUI
Co-Chair: A. NORONHA
Alcohol dependence/addiction is mediated by complex
neural mechanisms, which involve changes in a variety of
neurotransmitter systems resulting in adaptive changes
in neurocircuits. This minisymposium highlights recent
advances in understanding alcohol addiction from the
perspectives of both reward and stress systems. Speakers
will present studies on metaplasticity, dendritic spines,
optogenetics, and cross-talk of different signaling systems
involved in alcohol dependence/addiction.

314. Neural Phase Coding and Spike-Field
Coherence — CME
Mon. 8:30 AM - 11:00 AM — 207B
Chair: Z. NADASDY
Co-Chair: M. E. HASSELMO
Phase coding refers to the representation of information
by the phase of action potential firing relative to intrinsic
brain rhythms. This minisymposium covers recent
empirical support for phase coding in sensory cortical
and prefrontal cortical neurons, as well as the emerging
functions of oscillations in controlling information flow in
the hippocampus and in generating entorhinal grid cell
properties. New results provide compelling support for the
role of oscillations in neural coding.

8:35 314.02 Mechanisms for phase coding in entorhinal cortex
grid cells. M. E. HASSELMO. Boston Univ.

and place cells. N. BURGESS. Univ. Col. London.

hippocampus. L. L. COLGIN. Univ. of Texas at Austin.
