Definition of Neurofeedback Neurofeedback is a therapeutic technique that uses real-time displays of brain activity to train individuals to self-regulate their brain function. It is a form of biofeedback that focuses specifically on the brain’s electrical activity. How Neurofeedback Works In neurofeedback therapy, sensors are attached to a person’s scalp to measure the electrical activity […]
Definition of Neurodevelopmental Disorders Neurodevelopmental disorders refer to a group of conditions that impair the normal growth and development of the brain and nervous system. These disorders typically manifest in early childhood and persist throughout a person’s lifespan, causing significant impairments in various areas of functioning. Subtypes of Neurodevelopmental Disorders: Autism Spectrum Disorder (ASD): ASD

Neurodegenerative Disease: Definition: A neurodegenerative disease refers to a chronic and progressive condition characterized by the gradual deterioration and dysfunction of nerve cells (neurons) in the central nervous system (brain and spinal cord) or peripheral nervous system. It results in the degeneration or death of neurons, leading to various neurological impairments and symptoms. Subtypes of

Neurocognitive Disorders (NCDs) Definition: Neurocognitive Disorders (NCDs) are a group of conditions characterized by an impairment in cognitive functions such as thinking, memory, language, perception, and problem-solving. These disorders are primarily caused by a variety of neurodegenerative diseases, brain injuries, or other underlying medical conditions. Types of Neurocognitive Disorders: There are several types of NCDs,

Neuroanatomy: The study of the structure and organization of the nervous system. Nervous system: The complex network of specialized cells, tissues, and organs that transmit signals between different parts of the body to coordinate functions and responses. Structure: The physical organization and arrangement of the components that make up the nervous system. Organization: The hierarchical
Definition of Neuroadaptation: Neuroadaptation refers to the process by which the nervous system adjusts and changes in response to ongoing environmental stimuli or experiences. It involves various structural and functional modifications within the brain and the nervous system that occur over time. Subtitles: 1. Nature of Neuroadaptation: Neuroadaptation is a dynamic and intricate phenomenon that
Neurites Definition: Neurites are the long, thin extensions of a neuron that enable communication and connectivity within the nervous system. Anatomy of Neurites: Neurites consist of two main types of extensions: Axons: Axons are elongated structures that transmit electrical impulses away from the neuron’s cell body to other neurons, muscles, or glands. Dendrites: Dendrites are
Neurilemma A protective covering composed of Schwann cells that surrounds the axons of peripheral nerve cells.
Definition of Neurasthenia: Neurasthenia is a complex medical condition characterized by a state of chronic fatigue, mental exhaustion, and overall weakness. It is often associated with excessive stress, anxiety, and prolonged physical or mental exertion. This condition affects the nervous system, leading to various physical and psychological symptoms that significantly impair an individual’s ability to
Definition: Neural Stimulus refers to any form of physical, chemical, or electrical input that activates or modifies the activity of a neuron, stimulating the transmission of signals within the nervous system. Understanding Neural Stimulus: Neurons, the fundamental units of the nervous system, respond to various types of stimuli, which can originate from internal or external
