retention. Caffeine has a positive effect on learning and memory because it improves short term memory and increases reaction times. The caffeine travels to the hippocampus‚ which is the memory center in the human brain‚ which then works with the nervous system to retain the information‚ even if it’s only for a little while. The hippocampus is located in the medial temporal lobe of the brain. Caffeine stimulates the production of adrenaline‚ which is a hormone found in the pituitary gland. The pituitary

The amygdala also highlights important events in a memory‚ passing this information on to the hippocampus‚ telling it to store this memory. PTSD sufferers have a hyperactive amygdala that remains active for long periods‚ increasing stress and anxiety. The affected amygdala focuses on emitting stress signals and memory formation is halted as this is

Since it has been established that contextual fear conditioning‚ such as this task‚ requires the hippocampus‚ this task was used to test the effect on the hippocampus after the addition of young blood to the mice’s system. Whether or not mice learned the association was determined by measuring freezing time‚ or the amount of time they stood still. The results indicated that heterochronic
