What brain cortical area is responsible for sensations of a full urinary bladder and the feeling that your lungs will burst if you hold your breath too long? vestibular cortex gusatory cortex olfactory cortex visceral sensory area

Loss of ability to perform skilled motor activities such as piano playing, with no paralysis or weakness in specific muscles, might suggest damage to the ________. premotor cortex rubrospinal tracts primary motor cortex spinal cord

Why is the blood-brain barrier ineffective against alcohol? alcohol is water soluble it only prevents blood cells from reaching the brain it isn't, since alcohol cannot reach the brain alcohol is lipid soluble
