DESCRIPTION:Speaker: Juan Felipe Ramirez-Villegas\nhosted by Jozsef Csicsva
 ri\nAbstract: Intracortically-recorded brain signals display a rich variet
 y of transient activities: brief\, recurring episodes of deflection or osc
 illatory activities that reflect cooperative subcircuit mechanisms. These 
 network patterns of activity\, also called neural events\, span multiple s
 patio-temporal scales\, and are believed to be basic computing elements du
 ring cognitive processes such as learning and off-line memory consolidatio
 n. However\, both the large-scale and microscopic-scale cooperative mechan
 isms associated with these episodes remain poorly understood. Here\, we so
 ught to study the relationship between ongoing spontaneous neural events i
 n the hippocampus\, brainstem and thalamic structures by combining data fr
 om intracortical recordings\, multi-compartmental network models\, and fun
 ctional MRI (fMRI).In the first part of my presentation\, Ill talk about t
 he mechanisms underlying sharp wave-ripple (SWR) neural events in the hipp
 ocampus. In the second part of my talk\, Ill give an overview of our study
  of pontogeniculooccipital (PGO) waves\, and specifically their relationsh
 ip with hippocampal activity.
