AMYGDALA

Image
Amygdala Amygdala are almond-shaped groups of nuclei located deep and medially within the temporal lobes of the brain in complex vertebrates, including humans.[2] Shown in research to perform a primary role in the processing of memory, decision-making, and emotional reactions, the amygdalae are considered part of the limbic system.

HEADACHE

HEADACHE A headache or cephalalgia is pain anywhere in the region of the head or neck. It can be a symptom of a number of different conditions of the head and neck. The brain tissue itself is not sensitive to pain as it lacks pain receptors . Rather, the pain is caused by disturbance of the pain- sensitive structures around the brain. Nine areas of the head and neck have these pain- sensitive structures, which are the cranium (the periosteum of the skull), muscles, nerves , arteries and veins , subcutaneous tissues , eyes, ears , sinuses and mucous membranes . There are a number of different classification systems for headaches. The most well-recognized is that of the International Headache Society. Headache is a non-specific symptom, which means that it has many possible causes. Treatment of a headache depends on the underlying cause, but commonly involves pain killers .

CEREBRAL CORTEX

CEREBRAL CORTEX Functional Divisions of the Cerebral Cortex The cerebral cortex is responsible for many "higher-order" functions like language and information processing. Language centers are usually found only in the left cerebral hemisphere. For more information on language and differences between the right and left cerebral hemisphere, read about split brain experiments.

The cerebral cortex (cortex) is the thinking part of the brain where logic and judgment reside. It is the outer portion of the brain and is divided into lobes. Think of the cortex as the strategy center of the brain. The emotional center of the brain is the limbic system . It is located lower in the brain and is considered to be more rimitive than the cortex.

Working of Neuroplasticity

How Does Brain Plasticity Work ? The human brain is composed of approximately 100 billion neurons. Early researchers believed that neurogenesis, or the creation of new neurons, stopped shortly after birth. Today, it is understood that the brain possesses the remarkable capacity to reorganize pathways, create new connections and, in some cases, even create new neurons.

NEUROPLASTICITY

Neuroplasticity , also known as brain plasticity , is an umbrella term that encompasses both synaptic plasticity and non-synaptic plasticity—it refers to changes in neural pathways and synapses which are due to changes in behavior, environment and neural processes, as well as changes resulting from bodily injury.
