The memory centers that dopamine effects are called the amygdala and hippocampus. The amygdala contains the amygdaloid nuclei‚ which plays an important role in the modulation of mood (Mervaala et al.‚ 2000). The amygdala itself is an expanded region at the tail of the caudate nucleus and participates in the expression of emotions‚ control of behavioral activities‚ and development of moods (McKinley‚ 2006). The hippocampus is a nucleus located superior to the parahippocampal gyrus that connects to

pre-existing conditions of aged-brain at the molecular‚ structural‚ functional and cognitive levels. Since the proper functionality of the cognitive process is dependent on the hippocampus‚ it is the primary region that is negatively affected by age. Villedas’ group initially performed a genomic microarray analysis of the hippocampus in isochronic and heterochronic parabionts. Each particular parabionts exhibited a unique synaptic plasticity regulation. The Creb signaling pathway was also examined due

According to NIDA for Teens (NIDAT) chronic use of the drug can lead to damage in the hippocampus‚ a key component of the brain as well as an 8 point drop in IQ in recent studies. By damaging the hippocampus one may affect the ability to learn and can also damage memory as these are two of the main functions of the hippocampus. Analyzing the effects of THC which alters information received in the hippocampus can also explain the difficulty to create memories while high. With steady use these difficulties

The hippocampus‚ which is functionally related to vital behaviors and intellectual activities such as memory and learning‚ has been shown to be affected by lead‚ particularly in young children with an unknown mechanism [50]. For this reason‚ we selected the hippocampus as the target location in the present

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
