including humans. Cryptochromes are a group of proteins found in even the oldest of all plant species that becomeactive in the dark. These proteins are involved in signaling animals when it is time to migrate.
What part of the brain controls your level of arousal or consciousness and sleep? Which of the following brain regions is centrally involved in memory storage: A. Orbitofrontal cortex B. Insular cortex C. Dorsolateral prefrontal cortex ...
How is the secretion of adrenal cortex hormones regulated? What is the significance of the adrenal cortex? How different is it from the functions related to the adrenal medulla? Explain how the hypothalamus of the brain and the autonomic nervous syste...
The "pyro" in pyrogen is not a coincidence. "Pyro" comes from the Greek word for "fire." When these pyrogens reach the base of the brain, they run into the hypothalamus, which happens to be in charge of your body's temperature settings. Detecting pyrogens, the hypothalamus dials up the...
The hypothalamus and pituitary gland are responsible for visceral functions, body temperature and behavioral responses such as feeding, drinking, sexual response, aggression and pleasure. The cerebrum (also called the cerebral cortex or just the cortex) consists of the cortex, large fiber tracts (corp...
Migraines are thought to begin in the hypothalamus, a cone-shaped structure at the base of the brain. That is because many of the early symptoms align with known functions of the hypothalamus. Yawning, tiredness and mood changes – common features of migraine onset – are all controlle...
New research shows that neurons in the preoptic hypothalamus - the region of the brain that regulates sleep and body temperature - are rhythmically activated during non-rapid eye movement.
If the fear is intense enough, the amygdala will communicate with other parts of the limbic system such as the hypothalamus, to help initiate the fight or flight response, and the hindbrain (including the brainstem), to trigger a startle response such as quickly withdrawing your stung hand. It...
When the amygdala detects danger, it sends a distress signal to the hypothalamus, which then signals to your nervous system to trigger the fight-or-flight response. When this response is initiated, stress hormones (including adrenaline) flood your body, causing your heart to beat faster than ...
Science has produced not just one but several theoretical explanations of how humans can pull in sounds from their surroundings through the ears to develop a map of what animals or musical instruments or the like are nearby. Answer and Explanati...
