The orbitofrontal cortex: Neuronal activity in the behaving monkey

Neurons in the orbitofrontal cortex of the alert rhesus monkey possess highly coded information about which stimuli are present, as well as information about the consequences of the animal's own responses, which may constitute a neuronal mechanism for determining whether particular visual stimuli continue to be associated with reinforcement, aswell as providing for the modification of theAnimal's behavioural responses to such stimuli when those responses are no longer appropriate.

Topographic studies on visual neurons in the dorsolateral prefrontal cortex of the monkey

The prearcuate and inferior dorsolateral areas of the prefrontal cortex are functionally differentiated so that the lateral area's function is related to central vision, while that of the medial area to ambient vision.

Location of the polysensory zone in the precentral gyrus of anesthetized monkeys

It is suggested that the polysensory zone in the premotor cortex of macaques may contribute to the guidance of movement on the basis of tactile, visual and auditory signals.

Visuospatial properties of ventral premotor cortex.

It is suggested that "body-part-centered" coordinates provide a general solution to a problem of sensory-motor integration: sensory stimuli are located in a coordinate system anchored to a particular body part.

Coding of peripersonal space in inferior premotor cortex (area F4).

The functional properties of neurons in the caudal part of inferior area 6 (area F4) in awake monkeys are studied and it is concluded that space is coded differently in areas that control somatic and eye movements.

Ventral intraparietal area of the macaque: anatomic location and visual response properties.

A discrete area in the depths of the intraparietal sulcus containing neurons with response properties similar to those reported for the middle temporal area is described, called VIP, which suggests that it, like other visual areas in the dorsal stream, may be involved in the analysis of visual motion.

Motion sensitive cells in the macaque superior temporal polysensory area

This work has measured responses of visual movement sensitive neurons in the anterior part of the dorsal superior temporal sulcus of monkeys to stimulation caused by the animal's own active movements, and suggested that the studied neurons belong to a system that detects unexpected and hence behaviourally relevant sensory events.

Cortical afferents and efferents of monkey postarcuate area: an anatomical and electrophysiological study

It was shown that stimulation of area 7b (PF) gives rise to short-latency synaptic responses in postarcuate neurons, including some neurons with identified projections to MI, which are discussed in relation to the possible function of the postarcuates region of the premotor cortex in the sensory guidance of movement.

A bimodal map of space: somatosensory receptive fields in the macaque putamen with corresponding visual receptive fields

It is suggested that the bimodal cells in area 6, 7b, VIP, and the putamen form part of an interconnected system that represents extrapersonal space in a somatotopic fashion.



Enhancement of visual responses in monkey striate cortex and frontal eye fields.

The different characteristics of the enhancement instriate cortex and the observation of enhancement in the colliculus following ablation of striate cortex suggest that this cortical area is an unlikely source of the collicular enhancement.

Visual tracking and neuron activity in the post-arcuate area in monkeys.

A suggestion was made that in the FB area, after receiving the visual cue information, a function for the later movement direction and initiation are produced and sent to the motor apparatus within the brain so that effective tracking task can be performed.

Intrahemispheric cortical connexions and visual guidance of hand and finger movements in the rhusus monkey.

It is likely that the intrahemispheric cortical fibres to the frontal lobe play a role in visual guidance of relatively independent hand and finger movements in the rhesus monkey.

Receptive fields of single neurones in the cat's striate cortex

The present investigation, made in acute preparations, includes a study of receptive fields of cells in the cat's striate cortex, which resembled retinal ganglion-cell receptive fields, but the shape and arrangement of excitatory and inhibitory areas differed strikingly from the concentric pattern found in retinalganglion cells.

Receptive fields, binocular interaction and functional architecture in the cat's visual cortex

This method is used to examine receptive fields of a more complex type and to make additional observations on binocular interaction and this approach is necessary in order to understand the behaviour of individual cells, but it fails to deal with the problem of the relationship of one cell to its neighbours.
