“…In rats, as in primates, the PPC receives visual, auditory, and somatosensory inputs (Tees 1999;Reep et al 1994;Reep and Corwin 2009). By integrating these sensory inputs, the PPC can encode head-centered spatial information that is critical for spatial orientation and directed attention (Kesner et al 1989;Crowne et al 1992;Chen and Nakamura 1998;Reep and Corwin 2009), and this is consistent with the view that the PPC uses multimodal sensory information to modulate MI and guide motor output (Dijkerman and de Haan 2007).…”

Whisker and forelimb movements in rats have distinct behavioral functions that suggest differences in the neural connections of the brain regions that control their movements. To test this hypothesis, retrograde tracing methods were used to characterize the bilateral distribution of the cortical neurons that project to the whisker and forelimb regions in primary motor (MI) cortex. Tracer injections in each MI region revealed labeled neurons in more than a dozen cortical areas, but most labeling was concentrated in the sensorimotor areas. Cortical projections to the MI forepaw region originated primarily from the primary somatosensory (SI) cortex in the ipsilateral hemisphere. In contrast, most projections to the MI whisker region originated from the MI whisker region in the contralateral hemisphere. Tracer injections in the MI whisker region also revealed a higher proportion of labeled neurons in the claustrum and in the posterior parietal cortex. Injections of different tracers into the MI whisker and forepaw regions of some rats revealed a topographic organization of neuronal labeling in several sensorimotor regions. Collectively, these findings indicate that the MI whisker and forepaw regions receive different sets of cortical inputs. Whereas the MI whisker region is most strongly influenced by callosal projections, presumably to mediate bilateral coordination of the whiskers, the MI forepaw region is influenced mainly by ipsilateral SI inputs that convey somatosensory feedback.

“…The first cluster includes most of lateral extrastriate areas, while the second encompasses medial and parietal extrastriate cortex. Solid causal evidence confirms the involvement of these modules in ventral-like and dorsal-like computations – lesioning laterotemporal and posterior parietal cortex strongly impairs, respectively, visual pattern discrimination and visuospatial perception (Gallardo et al, 1979; McDaniel et al, 1982; Wörtwein et al, 1993; Aggleton et al, 1997; Sánchez et al, 1997; Tees, 1999). By comparison, functional understanding of visual processing in rodent extrastriate cortex is still limited.…”

Rodents are emerging as increasingly popular models of visual functions. Yet, evidence that rodent visual cortex is capable of advanced visual processing, such as object recognition, is limited. Here we investigate how neurons located along the progression of extrastriate areas that, in the rat brain, run laterally to primary visual cortex, encode object information. We found a progressive functional specialization of neural responses along these areas, with: (1) a sharp reduction of the amount of low-level, energy-related visual information encoded by neuronal firing; and (2) a substantial increase in the ability of both single neurons and neuronal populations to support discrimination of visual objects under identity-preserving transformations (e.g., position and size changes). These findings strongly argue for the existence of a rat object-processing pathway, and point to the rodents as promising models to dissect the neuronal circuitry underlying transformation-tolerant recognition of visual objects.DOI: http://dx.doi.org/10.7554/eLife.22794.001

“…I will concentrate on temporal cortex (TE2) and make comparisons with the (PPC). In rats using a visual object-place recognition task, TE2 lesioned rats fail to detect a visual object change, whereas PPC lesioned rats fail to detect a spatial location change (Tees, 1999) suggesting that the two cortical areas play a distinctive role in perceptual processing of visual versus spatial location information. Similar results were reported by Ho et al (2011) who showed that rats with TE2 lesions had object recognition problems at 20 min, but not at 5 min delays.…”

Memory is a complex phenomenon due to a large number of potential interactions that are associated with the organization of memory at the psychological and neural system level. In this review article a tripartite, multiple attribute, multiple process memory model with different forms of memory and its neurobiological underpinnings is represented in terms of the nature, structure or content of information representation as a set of different attributes including language, time, place, response, reward value (affect) and visual object as an example of sensory-perception. For each attribute, information is processed in the event-based, knowledge-based, and rule-based memory systems through multiple operations that involve multiple neural underpinnings. Of the many processes associated with the event-based memory system, the emphasis will be placed on short-term or working memory and pattern separation. Of the many processes associated with the knowledgebased memory system, the emphasis will be placed on perceptual processes. Of the many processes associated with the rule-based memory system the emphasis will be on short-term or working memory and paired associate learning. For all three systems data will be presented to demonstrate differential neuroanatomical mediation and where available parallel results will be presented in rodents, monkeys and humans.
