Effects of muscarinic blockade in perirhinal cortex during visual recognition.
Stimulus recognition in monkeys is severely impaired by destruction or dysfunction of the perirhinal cortex and also by systemic administration of the cholinergic-muscarinic receptor blocker,Expand

Neural signals in the monkey ventral striatum related to motivation for juice and cocaine rewards.
1. The results of neuropsychological, neuropharmacological, and neurophysiological experiments have implicated the ventral striatum in reward-related processes. We designed a task to allow us toExpand

The effects of physostigmine and scopolamine on recognition memory in monkeys.
The visual recognition of rhesus monkeys was evaluated by means of a delayed nonmatching-to-sample task with trial-unique objects. Each daily session consisted of two lists of 20 objects each, whichExpand

Neuronal Signals in the Monkey Ventral Striatum Related to Progress through a Predictable Series of Trials
Single neurons in the ventral striatum of primates carry signals that are related to reward and motivation. When monkeys performed a task requiring one to three bar release trials to be completedExpand

Comparison of the effects of scopolamine administered before and after acquisition in a test of visual recognition memory in monkeys.
The effect of scopolamine on visual recognition memory in rhesus monkeys was assessed with a delayed nonmatching-to-sample task employing trial-unique stimuli. During the acquisition phase, 40 sampleExpand

Choice behavior in rhesus monkeys: cocaine versus food.
Rhesus monkeys were allowed to choose between intravenous injections of cocaine and food reinforcement for lever pressing. A choice trial was available every 15 minutes continuously for 8 days. TheExpand

Strychnine-insensitive glycine binding sites have recently been shown to positively modulate N-methyl-D-aspartate (NMDA) receptors. In the present study, the effects on recognition memory ofExpand

Visual habit formation in monkeys with neurotoxic lesions of the ventrocaudal neostriatum
Visual habit formation in monkeys, assessed by concurrent visual discrimination learning with 24-h intertrial intervals (ITI), was found earlier to be impaired by removal of the inferior temporalExpand
