  9. 9. What Brain Does<br />Thalamus - decides where to send incoming sensory data (from eyes, ears, mouth, skin)<br />Sensory cortex - interprets sensory data<br />Hippocampus - stores and retrieves conscious memories; processes sets of stimuli to establish context<br />Amygdala - decodes emotions; determines possible threat; stores fear memories<br />Hypothalamus - activates "fight or flight" response<br />
  10. 10. Process of Creating Fear<br />This is called the low Road<br />Take No Chance<br />
  11. 11. Considered Decision<br />This is called High Road<br />
  12. 12. Nerve Paths Reaction to Fear Stimuli<br />Constricts PupilStimulus SalivationConstricts AirwaysSlows HeartbeatStimulate DigestionStimulate Gall Bladder BileDilates Blood Vessels in Intestines and RectumStimulates Urinary Bladder ContractionStimulates Penile ErectionStimulates EjaculationRelaxes Urinary Bladder Inferior mesentric GanglionStimulates Secretion of epinephrine and norepinephrineStimulates glucose production and releasesInhibits DigestionStimulates secretion of Sweet Glands Accelerates HeartbeatRelaxes Airways Constricts Blood vesselsInhibits Salivation Dilated Pupils<br />
  13. 13. Adrenal-cortical system <br />The endocrine system also operates like the nervous system to conduct information. The endocrine system uses blood vessels as information channels. Glands release into the bloodstream specific chemical messengers called hormones.. <br />The typical endocrine organ is a ductless gland that secretes chemical mediators directly into local blood vessels. to regulate the target organ's function. Hormones are also instrumental in regulating mood, growth development, tissue function, and metabolism, as well as sending messages and acting on them<br />
  14. 14. Twin action of Fear Stimuli<br />
  15. 15. Fear Necessity?<br />Fear and Excitement<br />Many people enjoy being afraid -- the arousal that comes with the fight-or-flight It's no wonder so many people go to see scary movies and ride roller coasters on dates.<br />Survival<br />If we couldn't be afraid, we wouldn't survive for long. We'd be walking into oncoming traffic, stepping off of rooftops and carelessly handling poisonous snakes. In humans and in all animals, the purpose of fear is to promote survival. In the course of human evolution, the people who feared the right things survived to pass on their genes. In passing on their genes, the trait of fear and the response to it were selected as beneficial to the race. He concluded that the entire fear response is an ancient instinct that has been untouched by the nuances of modern civilization.<br />It serves the same purpose today as it did when we might run into a lion while carrying water back from the river. Only now, we're carrying a wallet and walking down city streets. <br />
  16. 16. Common Fears<br />Most common fears .The top 10 list goes like this:<br />Terrorist attacks<br />Spiders<br />Death<br />Failure<br />War<br />Heights<br />Crime/Violence<br />Being alone<br />The future<br />Nuclear war<br />
  17. 17. Overcoming fear<br />Fear extinction involves creating a conditioned response that counters the conditioned fear response. While studies situate the amygdala as the location of fear memories formed by conditioning, scientists theorize that fear-extinction memories form in the amygdala but then are transferred to the medial prefrontal cortex (mPFC) for storage. The new memory created by fear extinction resides in the mPFC and attempts to override the fear memory triggered in the amygdala.<br />
  18. 18. Practical Tips to overcome Fear<br />It doesn't matter why you're scared. <br />Learn about the thing you fear. <br />Train. <br />Find someone who is not afraidTake her/him along when you try to conquer your fear -- it'll be much easier.<br />Talk about it<br />Play mind games with yourself. <br />Stop looking at the grand scheme. <br />Seek help. <br />
