Caffeine charges up a part of the brain – 2
Narrator: This is NIH Health Matters. I’m Joe Balintfy. An NIH study in rats has shown that caffeine stimulates a particular region of the brain which affects learning and memory.
Dudek: The caffeine caused an enhancement of the synaptic responses.
Narrator: Dr. Serena Dudek is the senior author of this NIH Study.
Dudek: Caffeine enhances synaptic connections in this one particular part of the brain at concentrations that really don't do anything elsewhere. So we think that this is where caffeine is working.
Narrator: Dr. Dudek adds that the region is likely to be a key site where cognitive function is modulated by the time of day. For more information, visit www.niehs.nih.gov. Health Matters is produced by the NIH, part of the U.S. Department of Health and Human Services.
