Cortical Dynamics of Contextually-Cued Attentive Visual Learning and Search: Spatial and Object Evidence Accumulation [PDF]

open access: yes, 2009
How do humans use predictive contextual information to facilitate visual search? How are consistently paired scenic objects and positions learned and used to more efficiently guide search in familiar scenes?

Perirhinal Cortex Neuronal Activity is Actively Related to Working Memory in the Macaque

open access: yesNeural Plasticity, 2002
Lesion studies suggest that the perirhinai cortex plays a role in object recognition memory. To analyze its role, we recorded the activity of single neurons in the perirhinal cortex in a rhesus monkey (Macaca mulatta) performing a delayed matching-to ...

NMDA receptor plasticity in the perirhinal and prefrontal cortices is crucial for the acquisition of long-term object-in-place associative memory [PDF]

open access: yes, 2008
A key process for recognition memory is the formation of associations between an object and the place in which it was encountered, a process that has been shown to require the perirhinal (PRH) and medial prefrontal (mPFC) cortices.

Propagation of Neocortical Inputs in the Perirhinal Cortex [PDF]

open access: yesThe Journal of Neuroscience, 2001
The perirhinal area is a rostrocaudally oriented strip of cortex in which lesions produce memory and perceptual impairments. It receives topographically organized transverse projections from associative neocortical areas and is endowed with intrinsic longitudinal connections that could distribute neocortical inputs in the rostrocaudal axis.

Effects of the Bee Venom Herbal Acupuncture on the Neurotransmitters of the Rat Brain Cortex

open access: yesJournal of Pharmacopuncture, 2001
In order to study the effects of bee venom Herbal Acupuncture on neurotransmitters in the rat brain cortex, herbal acupuncture with bee venom group and normal saline group was performed at LI4 bilaterally of the rat.

Integrative and distinctive coding of visual and conceptual object features in the ventral visual stream

open access: yeseLife, 2018
A significant body of research in cognitive neuroscience is aimed at understanding how object concepts are represented in the human brain. However, it remains unknown whether and where the visual and abstract conceptual features that define an object ...

Posterior white matter hyperintensities are associated with reduced medial temporal lobe subregional integrity and long-term memory in older adults

open access: yesNeuroImage: Clinical, 2023
White matter hyperintensities are a marker of small vessel cerebrovascular disease that are strongly related to cognition in older adults. Similarly, medial temporal lobe atrophy is well-documented in aging and Alzheimer’s disease and is associated with ...

Finding and not finding rat perirhinal neuronal responses to novelty:Rat perirhinal neuronal responses to novelty [PDF]

open access: yes, 2016
There is much evidence that the perirhinal cortex of both rats and monkeys is important for judging the relative familiarity of visual stimuli. In monkeys many studies have found that a proportion of perirhinal neurons respond more to novel than familiar

Muscarinic Receptors in Perirhinal Cortex Control Trace Conditioning [PDF]

open access: yesThe Journal of Neuroscience, 2009
Trace conditioning requires that a transient representation of the conditional stimulus (CS) persists during the time interval between the CS offset and the onset of the unconditional stimulus. According to one hypothesis, this transient CS representation is supported by endogenous activity in “persistent-firing” neurons of perirhinal cortex (PR).

In sight, in mind

open access: yeseLife, 2018
