The brain formed part of the central nervous system is the most complex organ made up of more than billions of nerve cells or neurons.
The functions of the brain are associated with the communication of trillions of connections called synapses and many specialized regions.
A neuron or nerve cell made of a cell body (also called soma), dendrites and an axon, is a cell in the nervous system that carries electrical impulses.
Neurons are core components of the brain, spinal cord and peripheral nerves that play an essential role to process and transmit information.
The function of neurons can be classified into 3 types
* The sensory neurons found within the nervous system that convert external stimuli from the organism's environment into internal electrical impulses. In other words, sensory neurons are activated by sensory input from the environment, including physical input of sound, touch, heat, or light.
* The motor neurons transmit information from the spinal cord to skeletal and smooth muscles,. In other words, motor neurons directly control all of the muscle movements.
* The interneurons connect the motor and sensory neurons. In other words, the interneurons transfer signals between sensory and motor neurons.
Believe it or not, there are more than 600 diseases of the central nervous system, including brain tumors, epilepsy, dementia such as Parkinson's disease and Alzheimer's disease and stroke.
The top 3 of neurological diseases include
* Alzheimer's disease (AD) is a neurodegenerative disease in the elderly, associated with the worsening of memory, thinking and behavior that severe enough to affect language communication, memory, lifelong hobbies or social life
* Bell's Palsy is a condition caused by sudden weakness or paralysis of facial muscles on one side of the face.
* Cerebral Palsy is a neurological disorder of children affecting a child's movement, motor skills, and muscle tone.
Ashwagandha also is known as Withania somnifera is a nightshade plant in the genus of Withania, belonging to the family Solanaceae, native to the dry parts of India, North Africa, Middle East, and the Mediterranean.
The herbal medicine has been considered as Indian ginseng and used in Ayurvedic medicine over 3000 years to treat tumors and tubercular glands, carbuncles, memory loss, and ulcers and considered as anti-stress, cognition-facilitating, anti-inflammatory, and anti-aging herbal medicine.
On finding a potent compound for the treatment of brain health, researchers examined the effects of Ashwagandha (WA) extracts (alcoholic and water) and their bioactive components for neuroprotective activities against oxidative stress in cultured glioblastoma and neuroblastoma cells.
According to the tested analysis, the extracts and one of the purified components at a low dose protected the glial and neuronal cells from oxidation, an important activity that promotes the neuron activity.
Furthermore, glutamate insult induced by the oxidative stress was also inhibited by the application of Ashwagandha (WA) extracts (alcoholic and water) and their bioactive components.
Based on the findings, researchers said, "the combinations of extracts and active component were highly potent endorsing the therapeutic merit of the combinational approach".
And, "Ashwagandha leaf derived bioactive compounds have neuroprotective potential and may serve as a supplement for brain health.s".
Taken altogether, Ashwagandha may be considered a functional herb for the promotion of brain functioning, pending to the result of larger sample size and multicenter study
