A dark mood causes a person to disengage from activities that stimulate the brain, such as hobbies and spending time with friends. Without this kind of stimulation, cognitive problems can emerge.
Small, bilateral lesions in many of these nuclei cause a global loss of consciousness. [25] Blood-oxygen-level-dependent fMRI have demonstrated normal patterns of brain activity in a patient in a vegetative state following a severe traumatic brain injury when asked to imagine playing tennis or visiting rooms in his/her house. [26]
Anything that causes epilepsy causes epileptogenesis, because epileptogenesis is the process of developing epilepsy. Structural causes of epilepsy include neurodegenerative diseases , traumatic brain injury , stroke , brain tumor , infections of the central nervous system , and status epilepticus (a prolonged seizure or a series of seizures ...
Once the neurons have reached their regional positions, they extend axons and dendrites, which allow them to communicate with other neurons via synapses. Synaptic communication between neurons leads to the establishment of functional neural circuits that mediate sensory and motor processing, and underlie behavior. [12]
This causes neurons to be damaged and the brain to be bruised. During this time, brain function is temporarily lost since the neurons are being damaged. Repeated instances of head trauma can lead to the development of lasting brain damage. [25] Chronic stress causes long-term changes in the structure and function of the brain.
Start small—whether it's slowly getting back to work, tidying up your living space, or tackling one small goal at a time. There's no need to rush. Taking it slow and adjusting gradually can make ...
Too much video game playing may cause vision problems. [11] Extensive viewing of the screen can cause eye strain, as the cornea, pupil, and iris are not intended for mass viewing sessions of electronic devices. Using video games for too long may also cause headaches, dizziness, and chances of vomiting from focusing on a screen.
Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded receptor potentials. [1] This process is called sensory transduction. The cell bodies of the sensory neurons are located in the dorsal root ganglia of the spinal cord ...
