BME, XI., Stoczek u. 2., St. ép., 320.-as terem. Monday, December 8th, 15:00. BME, Budapest, Stoczek u. 2, St. building, room 320. *Abstract: * Experimental evidence, such as task-dependent coherency between single-unit activity and local field potentials (LFPs), together with the dependency of action potential (AP) initiation on the subthreshold membrane oscillation (SMO) suggest that: i) the probability of action potentials is controlled by a common oscillatory mechanism; ii) the SMOs across individual neurons are not independent but rather form a coherent field of oscillations; and iii) nearly-synchronized SMOs may propagate through neuronal connections, creating a constant-phase gradient of SMO between neighbor neurons. Based on these assumptions, we formulated a model in which neurons encode information by the phase of APs relative to the SMO. The model consists of four stages: encoding with phase, gamma alignment, information transfer, and reconstruction. We demonstrated by means of simulations that information encoded by the phase of APs can reliably be transferred and reconstructed at distant target areas. Moreover, since the phase code is a compressed representation of the spatio-temporal features of the stimulus, it enables the transfer of information in parallel pathways without distortion from conductance differences. We illustrate by examples how phase coding may account for a number of unresolved physiological observations related to sparse coding, motion processing, phase precession, and invariance detection, as well as anatomical principles, such as the columnar organization and grid cell architecture. Furthermore, we show empirical evidence for stimulus-dependent phase coding in V1 from simultaneous single-unit and LFP recordings.* * Keresztes Attila BME-Kognitív Tudományi Tanszék BME-Cognitive Science Department akeresztes(a)cogsci.bme.hu <mailto:akeresztes@cogsci.bme.hu> keresztes.attila(a)gmail.com <mailto:keresztes.attila@gmail.com>

Tisztelt kollégák! December 3-án, szerdán fél 11-kor az MTA KFKI RMKI tanácstermében elõadást tart: Sidney Wiener CNRS-Collège de France LPPA, Paris, France Elõadásának témája: Neural correlates of learning in the hippocampo-prefrontal pathway The Wisconsin Card Sorting task is used to diagnose prefrontal damage in human patients. This task requiring self-generating set-shifting and rule creation was adapted for rats. Then we recorded local field potentials (LFPs) in hippocampus and prefrontal cortex as well as multichannel unit recordings in prefrontal areas PL/IL during learning and shifting between spatial and cue-guided strategies in a Y maze. The prefrontal neurons changed behaviorally correlated activity after rule changes and as the rat acquired new rules. Furthermore, during rule acquisition there was increased coherence of prefrontal and hippocampal LFPs in the theta band when the rat was at the fork of the Y maze, during response selection. With a new principal components analysis of unit ensemble co-activations permitting high temporal resolution, we determined that during slow wave sleep (SWS) that there was replay of prefrontal neural ensemble coactivations appearing during the awake learning experience. This mostly occurs during hippocampal sharp wave ripples, which correspond to periods of replay in the hippocampus also. Examination of prefrontal neuron modulation by hippocampal LFP theta oscillations demonstrated a subpopulation that had increased modulation during high coherence of hippocampal and prefrontal LFPs. Moreover, prefrontal cell assemblies formed during high coherence periods are reactivated during ripples occurring during sleep after learning the task. This suggests a new mechanism of increased inter-region communication during high LFP oscillatory coherence periods, facilitating selection of relevant information to be stored in long term memory.
