What is neurofeedback?Neurofeedback, or neurotherapy/neurobiofeedback, is a particular type of biofeedback (a process which helps us to gain awareness of our physiological functions through certain instruments) which shows real-time displays of brain activity in order to help teach self-regulation of brain function. The most common display method used is EEG, or electroencephalography.  

What is the neurohypophysis?   The pituitary gland is divided into two sections: the anterior lobe and the posterior lobe. The neurohypophysis is the name given to the posterior lobe (part) of the pituitary gland. The neurohypophysis stores and releases several hormones created by the hypothalamus - a small region at the base of the brain.     The antidi
