TL;DR: Enriched experience and training appear to evoke the same cascade of neurochemical events in causing plastic changes in brain, andufficiently rich experience may be necessary for full growth of species-specific brain characteristics and behavioral potential.

TL;DR: Evidence is summarized to suggest that exposure to novelty activates, at least in part, the same neural substrate that mediates the rewarding effects of drugs of abuse.

TL;DR: Physiological evidence from measurements of regional brain activity and of autonomic responses in normal subjects and behavioral observations from brain damaged patients are reviewed to propose that motor imagery shares neural mechanisms with processes used in motor control.

TL;DR: It is suggested that the actions of the perirhinal cortex and the hippocampus can be dissociated from one another.

TL;DR: In this paper, the effect of glucose on memory in patients with Alzheimer's disease (AD) was evaluated and it was shown that glucose could improve memory in a subset of patients that had abnormalities in their blood glucose regulation.

TL;DR: The evidence from brain-damaged and normal subjects suggests that face recognition is, indeed, 'special,' and provides some clues to the functional differences between face and object recognition.

TL;DR: The present findings are not consistent with the notion that nucleus accumbens dopamine depletion rendered the animals unable to climb the barrier, or set an absolute ceiling on the number of barrier crossings the animals could perform.

TL;DR: The results from these experiments help to confirm the importance of the anterior thalamic nuclei for allocentric tasks, but suggest that no region is pre-eminently important.

TL;DR: It is proposed that accelerated neural plasticity takes place during elevated post-training PS and is especially vulnerable to disruption at specific post- training time periods called PS windows.

TL;DR: It is demonstrated that under high light in an unfamiliar arena, the isolation compared to the socially reared rats showed a significantly (P < 0.01) higher level of social interaction, manifested as increases in aggressive and avoidance behaviours, and the effects of diazepam are altered.

TL;DR: The merits of the dopamine versus NMDA/PCP receptor mediated expression of PCP-induced psychosis are discussed, as well as the importance of selecting behavioral models which are best suited to model the expression of psychosis, rather than the motor effects of psychotomimetics.

TL;DR: It is illustrated that figure-ground assignment is realized early in visual processing, and that the pattern of early interactions also brings about an effective and sparse coding of visual shape.

TL;DR: Electrophysiological and lesion studies of monkeys indicate that the NBM may play a more important role in attention functions, impairments of which are an early and significant feature of patients with AD.

TL;DR: The data indicate that 3 alpha-Diol influences the expression of E2 and P-induced receptivity, and suggest that 3AlphaDiol, like other neurosteroids, may exert its effects on sexual behavior by actions at GBRs.

TL;DR: Because neurotrophic factors can protect the brain from a variety of traumatic insults, it is likely that they might also be effective in preventing or reversing glucocorticoid-induced damage to the hippocampus.

TL;DR: Results provide evidence for functional differences between the shell and core subregions, as well as for the involvement of the mesolimbic DA system in LI.

TL;DR: Two interconnected networks are distinguished that are associated with the inferotemporal cortex and includes areas of the ventral bank and fundus of the superior temporal sulcus, lateral FEF and ventral prestriate cortex, which emphasizes central vision, small accades and form recognition.

TL;DR: A surprising complexity is revealed in the way in which rats use their paws and digits in manipulating food and the results show that rats have limb preferences in spontaneous food handling and manipulatory dexterity is dependent upon the integrity of the forelimb area of motor cortex.

TL;DR: In this paper, the effects of 192 IgG saporin injection into the medial septal area (MSA), or nucleus basalis magnocellularis (NBM), and combined injections into the MSA and NBM, on water maze and radial arm maze performance in the male rat were investigated.

TL;DR: Evidence is provided for short- and long-term spatial memory deficits in Ts65Dn mice, a potential model for Down syndrome, using the 12-arm radial maze.

TL;DR: The present data provide additional support for an involvement of the two adhesion molecules L1 and NCAM in synaptic plasticity underlying memory storage.

TL;DR: It appears that most extrastriate visual areas, rather than each being devoted to the analysis of a specific basic visual attribute, perform several different tasks and thereby engage in more advanced and complex analyses than had been realized.

TL;DR: Investigating whether IL-6 immunoreactivity in plaques could already be found prior to the onset of neuritic changes and whether the presence of this cytokine is restricted to the later stages of plaque formation found that in AD an immunological mechanism may be involved in the transformation from diffuse to primitive plaques and in the development of dementia.

TL;DR: The results indicate that the anterior and posterior cingulate cortices are functionally dissociable, and suggest that they may form part of complementary, but competing, learning and memory systems.

TL;DR: It is proposed here that these areas and the anterior entorhinal cortex are designated as the temporal pole, a brain region which is specialized for both object recognition and memory.

TL;DR: Comparisons between groups of differing age and experience of migration suggested that both experience and age during the first year have an effect of relative hippocampal volume, which supports the view that changes in the hippocampus may be associated with migratory experience, whilst changes inThe telencephalon are not.

TL;DR: It is suggested that cholinergic neuromodulation participates in processing the CS in the gustatory cortex in CTA, either by encoding novelty at the cellular level, or by instructing the neural circuits to store the novel taste representation.

TL;DR: The above data suggest that fishes can implement multiple spatial learning strategies which have different neural substrata and are discussed in relation to the possible nature of the representation underlying each task.

TL;DR: Video recording of the chicks' behaviour while approaching the boxes showed that these lateral asymmetries reflect head and body turning associated to preferences in eye use, likely due to the different specializations of contralateral brain structures.
