Old age and cognition: Evaluation of a human short-term memory test with nonhuman primates and the memory-enhancing effects of nimodipine

A matrix problem, identical to that used with demented humans, was used to quantify the short-term memory capacities of five 33-year-old rhesus monkeys. Nimodipine at dosages of 1.0 and 3.0 mg/kg given orally ...

Recovery of function after brain damage: The effects of nimodipine on the chronic behavioral deficit

It is commonly found, although not often documented or studied, that while the performance of brain-injured individuals may achieve some measure of recovery, this recovery is nonetheless below the performance ...

Recovery of function after brain damage: The benefits of diets supplemented with the calcium channel blocker nimodipine

The acute administration of the dihydropyridine calcium channel blocker nimodipine has been shown to have a number of benefits with regard to recovery of function following brain injury and the behavioral dysf...

Recovery of function after brain damage: On withdrawals from the memory bank

The present research addressed the question of whether any change between the conditions of original preoperative learning and postoperative recovery would interfere with the availability and retrieval of the ...

Recovery of function after brain damage: On deposits to the memory bank

The availability of spared memories following neocortical injury has been shown to be related to the similarity of preoperative learning and postoperative recovery situations. In the present research we questi...

Recovery of function after brain damage: Support for the compensation theory of the behavioral deficit

It has recently been suggested that the behavioral deficit following brain injury is not exclusively the result of the neurological loss of the system components that had subserved the behavior in the normal a...

Infant posterior neocortical lesions do not induce visual responses in spared anterior neocortex

Infant posterior neocortex lesions enhance the significance of anterior neocortex for acquisition of a two-choice brightness discrimination. The present research was designed to determine if this result was an...

Recovery of function after brain damage: A theory of the behavioral deficit

The present discussion assumes that recovery of function is not an event but rather a process. When it occurs, this process bridges the gap between the occurrence of the brain injury and the reinstatement of a...

Recovery of function after brain damage: Toward understanding the deficit

The present research was based on the proposition that understanding the process of recovery of function after brain injury is ultimately determined by defining the nature of the behavioral dysfunction. For ex...

Recovery of function after brain damage: Different processes and the facilitation of one

The research reported here was concerned with the role of learning in recovery of function after brain damage. Three experiments were carried out. All of the experiments involved hooded rats trained in a two-c...

The primary visual system of the rat: A primer of its anatomy

The present review is concerned with the anatomy of the primary visual system of the rat. Of principal concern is the pigmented and the albino varieties which are commonly used for behavioral research. Data fr...

Arousal from sleep: The effects of the cognitive value of auditory stimuli

The present research describes the effects that different histories of positive reinforcement may have relative to the arousal produced during sleep by otherwise quite similar auditory stimuli. In general, the...

Arousal from sleep: The effects of the rise-time of auditory stimuli

The present research involves the methodological strategy of investigating sleep by determining an individual’s reaction to extrinsic stimulation. Particularly, the investigation was concerned with whether or ...

Waking performance decrements following minimal sleep disruption: The effects of habituation during sleep

The present research was concerned with whether the occurrence of habituation to auditory stimuli during sleep might attenuate the disruptive effects these stimuli can have on waking performance. Human subject...

The influence of preoperative learning on the recovery of a successive brightness discrimination

The recovery of a successive two-choice brightness discrimination following posterior neodecortication is significantly impaired if the reinforcement contingencies of the postoperative task are the reverse of ...
