Direct projections from CA1 to the superior temporal sulcus in the monkey, revealed by single axon analysis.

چکیده
Anterograde tracer injections in the middle sector of CA1 in macaque monkeys demonstrate a direct projection to the fundus of the anterior superior temporal sulcus, in area IPa. Terminations are predominantly in layer 3. With regard to both terminal and arbor configuration, these hippocampal-cortical connections are morphologically similar to corticocortical connections to temporal association cortex. This report provides additional evidence of direct CA1 connections to particular multimodal cortical areas.

Cortical inputs to the CA1 field of the monkey hippocampus originate from the perirhinal and parahippocampal cortex but not from area TE.
We determined the cortical regions that project directly to the CA1 field of the monkey hippocampus by injecting the retrograde tracers Fast blue, Diamidino yellow or WGA-HRP into CA1 and examining the distribution of labeled cells. In the temporal lobe, large numbers of retrogradely labeled cells were observed in the perirhinal and parahippocampal cortices. Only an occasional labeled cell, how...
متن کاملHeteromodal connections supporting multisensory integration at low levels of cortical processing in the monkey.
While multisensory integration is thought to occur in higher hierarchical cortical areas, recent studies in man and monkey have revealed plurisensory modulations of activity in areas previously thought to be unimodal. To determine the cortical network involved in multisensory interactions, we performed multiple injections of different retrograde tracers in unimodal auditory (core), somatosensor...
متن کاملReciprocal connectivity of identified color-processing modules in the monkey inferior temporal cortex.
The inferior temporal (IT) cortex is the last unimodal visual area in the ventral visual pathway and is essential for color discrimination. Recent imaging and electrophysiological studies have revealed the presence of several distinct patches of color-selective cells in the anterior IT cortex (AIT) and posterior IT cortex (PIT). To understand the neural machinery for color processing in the IT ...
متن کاملQuantitative analysis of the dendritic morphology of corticocortical projection neurons in the macaque monkey association cortex.
The polymodal association areas of the primate cerebral cortex are heavily interconnected and play a crucial role in cognition. Area 46 of the prefrontal cortex in non-human primates receives direct inputs from several association areas, among them the cortical regions lining the superior temporal sulcus. We examined whether projection neurons providing such a corticocortical projection differ ...
متن کاملPerirhinal and parahippocampal cortices of the macaque monkey: cortical afferents.
Neuropsychological studies have recently demonstrated that the macaque monkey perirhinal (areas 35 and 36) and parahippocampal (areas TH and TF) cortices contribute importantly to normal memory function. Unfortunately, neuroanatomical information concerning the cytoarchitectonic organization and extrinsic connectivity of these cortical regions is meager. We investigated the organization of cort...
