Neuromodulator A neuromodulator is a chemical substance that plays a crucial role in modifying the activity and function of neurons in the nervous system. Unlike neurotransmitters, which predominantly transmit signals from one neuron to another within a specific synapse, neuromodulators act more broadly, often affecting multiple neurons across different brain areas. Characteristics – Neuromodulators are […]
Neurological: The term neurological refers to anything related to the nervous system, its structure, function, or disorders. Structure: The neurological structure refers to the physical components of the nervous system, including the brain, spinal cord, and neurons. It encompasses the arrangement, connectivity, and organization of these elements. Function: Neurological function describes the activities and processes
Neurolinguistics: Neurolinguistics is a field of study that explores the relationship between language and the brain. It focuses on understanding how language is processed and produced in the human brain, as well as the neural mechanisms that underlie language acquisition, comprehension, and production. Key aspects of Neurolinguistics include: Language processing: Examines how the brain comprehends
Definition: Neuroleptic Malignant Syndrome (NMS) is a rare but potentially life-threatening neurological disorder that can occur as a reaction to certain medications used to treat psychiatric disorders. Overview: Neuroleptic Malignant Syndrome is characterized by a collection of symptoms that result from dysfunction of the body’s thermoregulation system and altered muscle control. It is most commonly

Neuroleptic Neuroleptic is a class of antipsychotic drugs used primarily to treat psychiatric disorders, such as schizophrenia. These medications work by altering the levels of certain chemicals in the brain to alleviate symptoms associated with psychosis, including delusions, hallucinations, and disorganized thinking. Mechanism of Action Neuroleptics act by blocking dopamine receptors in the brain, specifically
Neurolemmocytes Neurolemmocytes, also known as Schwann cells, are specialized cells that play an essential role in the peripheral nervous system (PNS). They are a type of glial cell that provides support and protection to nerve fibers. Structure and Function Neurolemmocytes are elongated cells that form a protective covering around axons in the PNS. They are
Neurogenic Adjective Neurogenic refers to any condition or process that originates within or affects the nervous system. It is derived from the combination of the word “neuro,” which pertains to the nerves, and “genic,” denoting origin. Neurogenic disorders or phenomena typically involve abnormal functioning or development of the nerves or neurons, leading to various neurological
Neurogenesis Neurogenesis refers to the process of generating new neurons or nerve cells in the brain. It involves the formation, development, and differentiation of neural stem cells into specialized neurons. This ongoing process is crucial for various aspects of brain function, including learning, memory, and the overall plasticity of the central nervous system. Process The
Neurofibromatosis Type 1 (NF-1) Definition Neurofibromatosis Type 1, commonly abbreviated as NF-1, is a genetic disorder characterized by the development of tumors called neurofibromas. It is one of the most common genetic disorders affecting the nervous system, occurring approximately in 1 out of every 3,000 individuals worldwide. Clinical Features NF-1 presents with various clinical features

Neurofibril A neurofibril is a microscopic structure found in neurons, which are the basic building blocks of the nervous system. Structure Neurofibrils are thread-like structures composed of protein filaments, primarily made up of microtubules and neurofilaments. They extend throughout the cytoplasm of the neuron and provide structural support. Function The main function of neurofibrils is
