  D.B. Matthews, A.L. MorrowEffects of acute and chronic ethanol exposure on spatial cognitive processing and hippocampal function in the rat Cited by:   To investigate if acute ethanol administration can facilitate the use of non-spatial memory performance, we trained rats when sober a task on an 8-radial arm maze that could be learned using either spatial or non-spatial information (Matthews et al., ).Specifically, animals were trained six trials/day to navigate to one particular goal arm for a food by: Acute low to moderate doses of ethanol produce reversible cognitive deficits affecting specifically the use of spatial information as the hippocampus is particularly vulnerable to the deleterious.

In contrast, acute ethanol impaired spatial learning on all days (p ≤ ) in adult animals. Interestingly, acute ethanol exposure in adolescent animals accounted for increasingly more variance across days, from 8% on Day 1 to 50% on Day 4 (see Table 1 for exact statistics), suggesting a change in the animals’ sensitivity over time.

Many occupations require operations during the night-time when the internal circadian clock promotes sleep, in many cases resulting in impairments in cognitive performance and brain functioning. Acute ethanol impairs spatial memory but not stimulus/response memory in the rat. Alcohol Clin Exp Res. ; – doi: /jtbx. Matthews DB, Simson PE, Best PJ. Ethanol alters spatial processing of hippocampal place cells: a mechanism for impaired navigation when intoxicated.
