Journal of Neuroscience, 1988 These experiments show that a synaptic response in brain, namely, the late inhibitory postsynaptic potential (IPSP) of hippocampal CA3 neurons in the rat hippocampal slice, was blocked by 2 compounds affecting guanosine triphosphate (GTP)-binding ...

Alterations in brain connectivity due to plasticity and synaptic delay
, 2017 Brain plasticity refers to brain's ability to change neuronal connections, as a result of environmental stimuli, new experiences, or damage. In this work, we study the effects of the synaptic delay on both the coupling strengths and synchronisation in a ...

Lithium ameliorates autistic-like behaviors induced by neonatal isolation in rats
Frontiers in Behavioral Neuroscience, 2014 Neonatal isolation is a widely accepted model to study the long-term behavioral changes produced by the early life events. However, it remains unknown whether neonatal isolation can induce autistic-like behaviors, and if so, whether pharmacological ...

Neuronal Synchronization Can Control the Energy Efficiency of Inter-Spike Interval Coding [PDF]
, 2018 The role of synchronous firing in sensory coding and cognition remains controversial. While studies, focusing on its mechanistic consequences in attentional tasks, suggest that synchronization dynamically boosts sensory processing, others failed to find ...

Experience-driven formation of parts-based representations in a model of layered visual memory [PDF]
, 2009 Growing neuropsychological and neurophysiological evidence suggests that the visual cortex uses parts-based representations to encode, store and retrieve relevant objects.

Neuropharmacology, 1997 By intracellular and whole cell recording in rat brain slices, it was found that bath-applied serotonin (5-HT) produces an increase in the frequency and amplitude of spontaneous excitatory postsynaptic potentials/currents (EPSPs/EPSCs) in layer V pyramidal cells of neocortex and transitional cortex (e.g. medial prefrontal, cigulate and frontoparietal).

Equilibrium Properties of Temporally Asymmetric Hebbian Plasticity [PDF]
, 2000 A theory of temporally asymmetric Hebb (TAH) rules which depress or potentiate synapses depending upon whether the postsynaptic cell fires before or after the presynaptic one is presented.

Membrane resonance enables stable and robust gamma oscillations [PDF]
, 2012 Neuronal mechanisms underlying beta/gamma oscillations (20-80 Hz) are not completely understood. Here, we show that in vivo beta/gamma oscillations in the cat visual cortex sometimes exhibit remarkably stable frequency even when inputs fluctuate ...

Gamma rhythms and beta rhythms have different synchronization properties [PDF]
, 2000 Experimental and modeling efforts suggest that rhythms in the CA1 region of the hippocampus that are in the beta range (12-29 Hz) have a different dynamical structure than that of gamma (30-70 Hz).
