Caffeine’s Effect on Learning and Memory Caffeine has a positive effect on learning and memory. Caffeine improves short term memory and increases reaction times. It also aids in helping children concentrate and improve their motor and memory attributes. Another effect is it enhances learning by increasing 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

desirable or dangerous. How does such recognition‚ which psychologists call preattentive perception‚ happen so accurately and quickly‚ even when the stimuli are complex and the context in which they arise varies? Much is known about the way the cerebral cortex‚ the outer rind of the brain‚ initially analyses sensory messages. Yet investigations are only now beginning to suggest how the brain moves beyond the mere extraction of features-how it combines sensory messages with past experience and with expectation

AE3 Allen How males and females communicate Human is more advanced than other animals‚ it is that human can use tools and use their own languages. There are many kinds of different languages in the world. Human beings are made up of men and women‚ but they use the different languages to communicate. This essay will explain how males and females communicate. There are several ideas about communication for males. First of all‚ when males play game‚ they like to join in large groups. For example

of the brain. It is divided into 2 parts (halves) called the left and right cerebral hemispheres. The 2 hemispheres are connected by a bridge of nerve fibres called the corpus callosum. The right half of the cerebrum (right hemisphere) controls the left side of the body. The left half of the cerebrum (left hemisphere) controls the right side of the body. The outer surface of the cerebrum is called the cerebral cortex or grey matter. It is the area of the brain where nerve cells make connections

The globus pallidus and the substantia nigra are the primary output structures‚ sending inhibitory output signals to the thalamus and brainstem.

During some phases of sleep‚ the neurons in the cerebral cortex regenerate. If sleep is interrupted so that this regeneration cannot occur‚ speech may be affected‚ since the temporal lobe of the brain is what controls speech. People who do not get enough sleep often have slurred speech. There is also measurably
