memory is not a single entity. it is a gift of mother nature, the ability of living organisms to retain and to utilize acquired knowl- edge. memory is precisely related to learning, in that memory in biolog- ical systems entails learning and that learning implies retention of such information. memory can be divided into multifaceted systems. the renaissance of encephalon compatible learning app...
BACKGROUND Impairments of memory are commonly reported by people with traumatic brain injuries (TBI). Such deficits are persistent, debilitating, and can severely impact quality of life. Currently, many do not routinely receive follow-up appointments for residual memory problems following discharge. METHODS/DESIGN This is a multi-centre, randomised controlled trial investigating the clinical ...
objective(s): there is controversial evidence about the effect of methamphetamine (meth) on spatial memory. we tested the time- dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze. materials and methods: rats were sensitized to meth (2 mg/kg, daily/5 days, sc). rats were trained in water maze ...
abstract aim and background: evaluation of cognition is fundamental for every comprehensive epilepsy program. we sought to conduct this study to assess memory state of patients with refractory temporal lobe epilepsy before decision for epilepsy surgery. method and materials: in a case-control study, 20 patients with right temporal lobe epilepsy and 20 patients with left temporal lobe epilepsy w...
Traumatic brain injury (TBI) results in both acute and chronic disruption of cognitive ability that may be mediated through a disruption of hippocampal circuitry. Experimental models of TBI have demonstrated that cortical contusion injuries can result in the loss of specific neurons in the CA3 subfield of the ipsilateral hippocampus, resulting in partial loss of afferents to the CA1 subfield. N...
Single night sleep recordings in closed head injury patients 6 to 59 months after injury revealed less stage 1 and a greater number of awakenings compared to age matched controls. Neither the time spent in REM sleep nor the Wechsler Memory Quotient were related to complaints of decreased or absent dreaming following injury. The proportion of REM and number of awakenings, however, showed a moder...
