Behavioral performance modulates spike field coherence in monkey prefrontal cortex.

To investigate neuronal processing during short-term memory, we analyzed behavior-related modulations of coupling between signals on two spatial scales: first, very local multiunit activity and second, local field potentials. Coupling was assessed by spike field coherence using a new approach to overcome limitations in cases of low firing rates. We demonstrate the reliability of our approach wi...

Local field potentials primarily reflect inhibitory neuron activity in human and monkey cortex

The local field potential (LFP) is generated by large populations of neurons, but unitary contribution of spiking neurons to LFP is not well characterised. We investigated this contribution in multi-electrode array recordings from human and monkey neocortex by examining the spike-triggered LFP average (st-LFP). The resulting st-LFPs were dominated by broad spatio-temporal components due to ongo...

Local field potential reflects perceptual suppression in monkey visual cortex.

Neurophysiological and functional imaging experiments remain in apparent disagreement on the role played by the earliest stages of the visual cortex in supporting a visual percept. Here, we report electrophysiological findings that shed light on this issue. We monitored neural activity in the visual cortex of monkeys as they reported their perception of a high-contrast visual stimulus that was ...

Behavioral function improvement of prefrontal cortex in treated depressed rats by ECT and ketamine

Background and Objective: Depression is one of the most prevalent mental disorders. Electroconvulsive Therapy (ECT) is one of the effective methods for treatment of depression. Regarding the stimulatory effect of glutaminergic system on the progression of depression, the effect of ketamine as one of the most important inhibitors of this system has been investigated on the effectiveness of ECT. ...

Search target selection in monkey prefrontal cortex.

To explore a visual scene, the brain must detect an object of interest and direct the eyes to it. To investigate the brain's mechanism of saccade target selection, we trained monkeys to perform a visual search task with a response delay and recorded neuronal activity in the prefrontal (PF) cortex. Even though the monkey was not allowed to express its choice until after a delay, the response fie...
