Theta oscillations represent the" on-line" state of the hippocampus. The extracellular
currents underlying theta waves are generated mainly by the entorhinal input, CA3 …

The primary psychoactive ingredient in cannabis, Δ9-tetrahydrocannabinol (Δ9-THC), affects
the brain mainly by activating a specific receptor (CB1). CB1 is expressed at high levels in …

The hippocampus is one of a group of remarkable structures embedded within the brain's
medial temporal lobe. Long known to be important for memory, it has been a prime focus of …

The primary aim of this review is to examine evidence for a functional role of gamma and
theta oscillations in human episodic memory. It is proposed here that gamma and theta …

This paper focuses on high‐frequency (gamma band) EEG activity, the most characteristic
electrophysiological pattern in focal seizures of human epilepsy. It starts with recent …

This review assesses the parallel data on the role of gamma‐aminobutyric acid (GABA) in
depression and anxiety. We review historical and new data from both animal and human …

Defining a bio-electrical marker for the brain area responsible for initiating a seizure remains
an unsolved problem. Fast gamma activity has been identified as the most specific marker …

In the brain, highly connected and heterogeneous GABAergic cells are crucial in controling
the activity of neuronal networks. They accomplish this task by communicating through …

Recurrent inhibitory loops are simple neuronal circuits found in the central nervous system,
yet little is known about the physiological rules governing their activity. Here we use …

Neostriatal cholinergic interneurons are believed to be important for reinforcement-mediated
learning and response selection by signaling the occurrence and motivational value of …
