Fear is an instinctive response triggered by the amygdala and hypothalamus when danger is sensed. This causes the release of hormones like adrenaline that prepare the body for the "fight or flight" response through increased heart rate, blood pressure, sweating and other physiological changes. Fear memories are stored and can cause reflex reactions upon repetition of fearful events. While some fears like heights or spiders are common, others can be more unique. Overcoming fear involves exposing oneself to the feared object in a gradual, controlled manner to build new memories in the prefrontal cortex that can override the old fear memories stored in the amygdala. Practical tips include learning about the feared object, facing it with support, positive self

- 2. DefinitionInstinctive Response to Danger.
- 3. Biologically what is fearAs a first response to fear Amygdala and hypothalamus are activated .Chemicals such as Adrenaline stress hormone cortisol are release in blood stream
- 4. This results inRapid heart rateIncreased blood pressureTightening of musclesSharpened or redirected sensesDilation of the pupils (to let in more light)Increased sweating
- 5. ReactionRemember the incident clearlyOn repetition of incident reaction will be reflex actionStrength will be great may even lift a car without pain

- 9. What Brain DoesThalamus - decides where to send incoming sensory data (from eyes, ears, mouth, skin)Sensory cortex - interprets sensory dataHippocampus - stores and retrieves conscious memories; processes sets of stimuli to establish contextAmygdala - decodes emotions; determines possible threat; stores fear memoriesHypothalamus - activates "fight or flight" response

- 13. Adrenal-cortical system 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.. 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

- 15. Fear Necessity?Fear and ExcitementMany 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.SurvivalIf 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.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.
- 16. Common FearsMost common fears .The top 10 list goes like this:Terrorist attacksSpidersDeathFailureWarHeightsCrime/ViolenceBeing aloneThe futureNuclear war
- 17. Overcoming fearFear 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.
- 18. Practical Tips to overcome FearIt doesn't matter why you're scared. Learn about the thing you fear. Train. Find someone who is not afraidTake her/him along when you try to conquer your fear -- it'll be much easier.Talk about itPlay mind games with yourself. Stop looking at the grand scheme. Seek help.
