Neuronal activity in the monkey hippocampus was recorded while the monkey sat in a rotatable cab which it could cause to move from one location to another by pressing bars, and while it was presented various visual stimulation from several horizontal directions (directional stimulation). Of 174 hippocampal neurons recorded, 20 were selective to direction of the stimulus without place relation. Responses of these neurons could be described in egocentric coordinates for some and allocentric… Expand

Monkey hippocampal neuron responses related to spatial and non-spatial influence
Activity in the monkey hippocampal formation was analyzed during movement guided by auditory and visual cues and the results suggest HF gating of incoming non-spatial information, depending on information about location. Expand
Place and contingency differential responses of monkey septal neurons during conditional place-object discrimination
The results suggest that septal nuclei are involved in integrating spatial information, conditional place-object relations, and reward/nonreward contingency. Expand
Single Neuron Activity in Human Hippocampus and Amygdala during Recognition of Faces and Objects
During encoding and recognition, single neurons in the medial temporal lobe discriminated faces from inanimate objects and constructed a "cognitive map" of stimulus attributes comparable to the map of the spatial environment described in the rodent hippocampus. Expand
Spatial responsiveness of monkey hippocampal neurons to various visual and auditory stimuli
The results suggest that these hippocampal neurons may be involved in identification of relations among various kinds of stimuli in different spatial frameworks (egocentric or allocentric) and this identification may be developed from multiple sensory modalities. Expand
Representation of place by monkey hippocampal neurons in real and virtual translocation
The present results strongly suggest that activity patterns of the HF and PH neurons represent spatial information and might provide a neurophysiological basis for a cognitive map. Expand
Task-dependent representations in rat hippocampal place neurons.
Recording hippocampal complex-spike cells from rats that performed three types of place learning tasks in a circular open field with the use of intracranial self-stimulation suggests two strategies for how hippocampal neurons incorporate an incredible variety of perceptions into a unified representation of the environment. Expand
Active Spatial Information Processing in the Septo‐Hippocampal System
A cognitive mapping system represented in the HF plays a pivotal role in active computation for path finding, consistent with recent human PET studies that indicated HF involvement in recalling routes and landmarks. Expand
Spatial- and Task-Dependent Neuronal Responses during Real and Virtual Translocation in the Monkey Hippocampal Formation
The results suggest that theHF and PH are crucial in allocentric information processing and, moreover, that the HF can encode different reference frames that are context or task-dependent, which may be the neural basis of episodic memory. Expand
The Representation of Space and the Hippocampus in Rats, Robots and Humans
It is proposed that the locations of goals in an environment is stored downstream of the place cells, in the subiculum, and in addition to firing rate coding, place cells may use phase coding relative to the theta rhythm of the EEG. Expand
Neuronal activity in the primate hippocampal formation during a conditional association task based on the subject's location
The hippocampal formation (HF) functions in two domains of memory: spatial and nonspatial associative memory. The HF includes the hippocampus proper, the dentate gyrus, and the subicular complex.Expand

Not only is spatial information processed by the primate hippocampus, but it can be combined with information about which stimuli have been seen before, and the ability of the hippocampus to form such conjunctions may be an important property for its role in memory. Expand
Activity of hippocampal formation neurons in the monkey related to a conditional spatial response task.
The results show that single hippocampal neurons respond to combinations of the visual stimuli and the spatial responses with which they must become associated in conditional spatial response tasks and are consistent with the suggestion that part of the mechanism of this learning involves associations between visual stimulus and spatial responses learned by single hippocampusal neurons. Expand
Recognition of egocentric and allocentric visual and auditory space by neurons in the hippocampus of monkeys
The results are consistent with a role of the hippocampus in spatial memory and three types of neurons were identified by rotating the animals: egocentric and allocentric, and indeterminate. Expand
Spatial selectivity of rat hippocampal neurons: dependence on preparedness for movement.
Information from the motor programming systems (or "motor set") may contribute to coding of spatial location by hippocampal neurons, and hippocampal neuronal activity may reflect the association of movements with their spatial consequences. Expand
Single neuron activity in dorsolateral prefrontal cortex of monkey during operant behavior sustained by food reward
The data suggest that neurons in the dorsolateral prefrontal cortex have multiple functions related to all phases of complex, learned feeding behavior, and functional roles of the prefrontal cortex and the lateral hypothalamus in development of feeding behavior are discussed. Expand
Place navigation impaired in rats with hippocampal lesions
It is reported that, in addition to a spatial discrimination impairment, total hippocampal lesions also cause a profound and lasting placenavigational impairment that can be dissociated from correlated motor, motivational and reinforcement aspects of the procedure. Expand
A selective mnemonic role for the hippocampus in monkeys: memory for the location of objects
The results suggest that although the hippocampus and amygdala appear to participate equally in object recognition, only the hippocampus is critical for the rapid formation of object-place associations. Expand
The hippocampus as a spatial map. Preliminary evidence from unit activity in the freely-moving rat.
Preliminary observations on the behaviour of hippocampusal units in the freely moving rat provide support for this theory of hippocampal function. Expand

A neural model is presented, based largely on evidence from studies in monkeys, postulating that coded representation of stimuli are stored in the higher-order sensory (i.e. association) areas of theExpand
Hippocampal place cells: stereotypy and plasticity
Findings suggest hippocampal place cell firing, although highly influenced by spatial and directional features of the environment, can readily change under conditions in which significant stimuli are added or removed from those locations. Expand
