Rats with perirhinal cortex lesions were sequentially trained in a rectangular water tank on a series of 3 visual discriminations, each between mirror-imaged stimuli. When these same discriminations were tested concurrently, the rats were forced to use a configural strategy to solve the problems effectively. There was no evidence that lesions of the perirhinal cortex disrupted the ability to le...

The perirhinal cortex and hippocampus have close anatomical links and it has, therefore, been proposed that they have important, coordinated roles in memory. This review examines the relative role of these structures in spatial memory tasks that are known to be hippocampal-dependent. The published lesion data gives a mixed picture, as only some studies detect spatial deficits after perirhinal c...

Damage to the perirhinal cortex (PRh) in rats impairs anterograde object-recognition memory after retention intervals of up to several hours, but there is little direct evidence to link PRh function to object-recognition abilities after substantially longer intervals that span several days or weeks. We assessed the effects of PRh lesions on anterograde object recognition using a novel-object pr...

The role of the postrhinal cortex (POR) and the perirhinal cortex (PER) in processing relational or contextual information was examined with Pavlovian fear conditioning. Rats with electrolytic or neurotoxic lesions of the POR or PER were tested in 2 contextual fear conditioning paradigms. In Experiment 1, electrolytic lesions of the POR or PER produced impairments in contextual fear conditionin...

In the delayed match-to-sample task, responses of inferior temporal neurons to adjacent stimuli in the sequence are correlated to each other when the monkey was trained repeatedly with the sequence of visual stimuli, although the monkey was not required to associate the stimuli with each other. This correlation, however, is not observed for a monkey with lesions of the rhinal cortex, which is n...

Background: There is need to evaluate influence of weather changes on blood pressure in human population that has often been ignored in clinical practice guidelines. Objectives: Present study was planned to find the seasonal variation of blood pressure. Methods: Seasonal variation in blood pressure was examined in 1081 participants of age 18 years and over from both genders, 540 from rural and ...

To compound this, examples of abnormal behavior in high-integrity systems are few and far between; usually, there are insufficient examp...
