How are parts of the brain related to brain function?
Housed in the inner brain, the hypothalamus, thalamus, hippocampus and basal ganglia represent another segment of the forebrain. These organs and nerve cells work together to transfer signals between the brain and the spinal cord. The inner brain is responsible for emotions, perceptions and movements.
Where is the brain located?
The brain is located in the head, usually close to the sensory organs for senses such as vision. The brain is the most complex organ in a vertebrate’s body. In a human, the cerebral cortex contains approximately 14-16 billion neurons, and the estimated number of neurons in the cerebellum is 55-70 billion.
What are the parts and functions of the brain?
The brain has three main parts: the cerebrum , cerebellum and brainstem. Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
What is the function of the brain lobes?
Each brain lobe has a specific function. Functions of the cerebral cortex lobes involve everything from interpreting and processing sensory information to decision-making and problem-solving capabilities. In addition to the parietal lobes, the lobes of the brain consist of the frontal lobes, temporal lobes, and occipital lobes .
What is the hippocampus and its function?
The hippocampus is a central structure within the brain of vertebrates, responsible for handling the storage of memories and the linking of memories to sensations. Another function of the hippocampus is aiding in navigation by enabling spatial memory. There are two hippocampi in the brain, one in each cerebral hemisphere.
What are the symptoms of damage to the hippocampus?
In Alzheimer’s disease the hippocampus is one of the first regions of the brain to suffer damage; memory problems and disorientation appear among the first symptoms. Damage to the hippocampus can also result from oxygen starvation (hypoxia), encephalitis, or medial temporal lobe epilepsy.
Can You Grow Your hippocampus?
Stress reduction and meditation, for example, have been shown to substantially expand the volume of hippocampus. Treatment of sleep apnea, with using a CPAP machine, is another way you can grow your hippocampus.
