Perirhinal Cortex Lesions Impair Context Aversion Learning [PDF]
Learning & Memory, 2003 Rats with perirhinal cortex lesions were compared with sham controls on a conditional discrimination in which saccharin was paired with LiCl in context 1, but paired with saline in context 2. Perirhinal-lesioned rats were slightly slower to acquire the discrimination but reached control levels by the end of acquisition.

Developmental Cognitive Neuroscience, 2015 To investigate the role of the perirhinal cortex on the development of recognition measured by the visual paired-comparison (VPC) task, infant monkeys with neonatal perirhinal lesions and sham-operated controls were tested at 1.5, 6, 18, and 48 months of

Change in background context disrupts performance on visual paired comparison following hippocampal damage [PDF]
, 2009 The medial temporal lobe plays a critical role in recognition memory but, within the medial temporal lobe, the precise neural structures underlying recognition memory remain equivocal. in this study, visual paired comparison (VPC) was used to investigate

Perirhinal cortex hyperexcitability in pilocarpine‐treated epileptic rats [PDF]
Hippocampus, 2011 AbstractThe perirhinal cortex (PC), which is heavily connected with several epileptogenic regions of the limbic system such as the entorhinal cortex and amygdala, is involved in the generation and spread of seizures. However, the functional alterations occurring within an epileptic PC network are unknown.

Frontiers in Human Neuroscience, 2014 Recent research suggests that the medial temporal lobe (MTL) is involved in perception as well as in declarative memory. Amnesic patients with focal MTL lesions and semantic dementia patients showed perceptual deficits when discriminating faces and ...

Medial temporal lobe contributions to intra-item associative recognition memory in the aging brain [PDF]
, 2014 Aging is associated with a decline in episodic memory function. This is accompanied by degradation of and functional changes in the medial temporal lobe (MTL) which subserves mnemonic processing.

Auditory trace fear conditioning requires perirhinal cortex [PDF]
Neurobiology of Learning and Memory, 2008 The hippocampus is well-known to be critical for trace fear conditioning, but nothing is known about the importance of perirhinal cortex (PR), which has reciprocal connections with hippocampus. PR damage severely impairs delay fear conditioning to ultrasonic vocalizations (USVs) and discontinuous tones (pips), but has no effect on delay conditioning to

Homosexual women have less grey matter in perirhinal cortex than heterosexual women.
PLoS ONE, 2007 Is sexual orientation associated with structural differences in the brain? To address this question, 80 homosexual and heterosexual men and women (16 homosexual men and 15 homosexual women) underwent structural MRI.

Frontiers in Systems Neuroscience, 2016 The lateral prefrontal cortex is known for its contribution to working memory (WM) processes in both humans and animals. Yet, recent studies indicate that the prefrontal cortex is part of a broader network of interconnected brain areas involved in WM ...

Disambiguation of visual stimuli correlates with activity in bilateral medial temporal lobe structures [PDF]
Romanian Journal of Neurology, 2013 We are organisms adapted to recognize patterns around us in order to avoid ambiguity and indecision and there are inter-individual differences at this level.
