About 3 pounds
What does the Parietal Lobe Involve?
It involves your sense of touch and feeling of pain along with signals from your eyes and ears.
What is the midbrain responsible for?
Awareness of body parts.
What are the four lobes of the cerebrum and their function?
Frontal lobe controls conscious thought, and executive function over the brain. The Parietal lobe processes sensory inputs and relays them to their parts of the brain. The occipital lobe specifically processes vision. Finally, the temporal lobe processes language input, and some memory.
What does your medulla oblongata do.
It plays an essential role in passing messages between your spinal cord and brain

What is a fixed mindset?
believe that it can only be fixed not changed
largest part of your brain?
how does the brain develop
back to front
how do we perceive pain
We feel pain via nerve receptors attached to our spinal cord
what part of the brain keeps memories?
the amygdala, the hippocampus, the cerebellum, and the prefrontal cortex
What is a Neurotransmitter?
often referred to as the body's chemical messengers
In teens, what influence is stronger over the cortex?
what is the limbic system?
a large group of brain structures responsible for motivation, emotion, learning, and memory.
What triggers neurotransmitters
the arrival of nerve impulses at the presynaptic terminal
Where are neurotransmitters made
Neurotransmitters are made in the cell body of the neuron and then transported down the axon to the axon terminal
How do neurotransmitters carry information
The neurotransmitters carry the message with them into the synapse
which part of the brain is the last to develop?
The prefrontal cortex
What are the functions of the Hindbrain, Midbrain, and Forebrain?
"Hindbrain~ Respiratory rhythm, Motor Activities Midbrain~ Regulation of temperature,
What is Myelination?
Myelination is the process of coating axons with a fatty coating. It protects the neuron and helps conduct signals more efficiently.
What is a synapse?
When one neuron's terminal connects with another neuron's dendrite.
what is the responsibility of the limbic system?
the limbic system is responsible for emotions and how we react to situations, it does not fully develop into our 20s
Why is the prefrontal cortex important?
The cortex is responsible for decision making.
What is a neurotransmitter?
A neurotransmitter acts as a chemical messenger inside the brain.There are 100 different types of neurotransmitters, and they are released from the synapse. When they reach the target cell, they attach to that cell's receptors.
What are the two different types of neurons?
Presynaptic and Postsynaptic
What is the Rewards System?
"Your reward system evaluates the likelihood that an activity will have a positive outcome.
why is fear useful for the brain?
Fear is a survival mechanism, the amygdala is the brain's threat center that responds to danger in short and long paths. A memory is created that may influence a person if a similar situation occurs in the future
What does dopamine do?
It interacts with the pre-frontal cortex to organize behavior, produces attention, stimulation, and focus to get something you want.
what is various states of the brain?
there is conscious, pre conscious, and unconscious
all mental processes of which we are aware
all mental processes that are inaccessible to the conscious mind
all mental processes that an individual is not but can easily be brought to consciousness
closed brain injury
injury to the brain caused by over movement of the brain within the skull usually caused by being struck by a object
penetrating brain injury
injury to brain caused by foreign object entering the skull causes included getting struck by sharp object
include breathing, heartbeat, and digestion
wat is responsible for conscious thought
what is Unconsciousness
the interruption of awareness of oneself and ones surroundings
What is cardiac arrest ?
Sudden, unexpected loss of heart function, breathing and consciousness.
what is an AED used for?
Delivers an electrical shock to help the heart re-establish an effective rhythm.
What is the difference between cardiac arrest and a heart attack ?
A heart attack is when blood flow to the heart is blocked and cardiac arrest is when the heart suddenly stops beating.
What is biofeedback?
"The process of recognizing what is going on in your body and bringing
you are not active."
Resting Heart Rate
Define Target Heart Rate?
A Target Heart Rate is the speed of the heartbeat measured by the number of contractions (beats) (BPM)
What system has the process of breaking down food?
The digestive system
Why do cells need oxygen?
Every cell in the body requires oxygen to function. No breathing = No oxygen = No brain function
What System is most important in your body for everyday needs, and what does it do?
The Nervous system , and it is responsible for every movement and action your body makes
What happens when we exercise?
O2 increases, rapid breathing, heartrate rises, blood flows to active muscles
Why is CPR important?
It can continue to provide oxygen to the brain and heart after the heart has stopped beating, which can triple chances of survival
What is the difference between cardiac arrest and a heart attack?
Cardiac arrest is the sudden stop of the heart and a heart attack is where there is a blocked artery and oxygen/blood can't move through
Is it possible to calm our involuntary responses?
Yes, using biofeedback you can put some processes under voluntary control to reduce stress and anxiety
What is memory?
Memory is the reactivation of a specific group of neurons.
What is declarative memory?
An explicit memory, or memories of facts and events
How are memories formed?
Synaptic plasticity is the term used to describe how strong the connection between neurons and connections that are used often, called active connections, become stronger than those not used at all. Memory formation depends on how strong the connections between these neurons are.
What is a nondeclarative memory?
An implicit memory, or procedural memory or classical conditioning
What is memory consolidation and when does it occur?
Storage from working and long term memory. It occurs during sleep
What role does fear play when it comes to memory?
Understanding how the amygdala processes fear is important. The amyldala plays a key role in forming new memoires specifically related to fear. The amygdala plays a part in how memories are stored because storage is influenced by stress hormones.
Where are memories stored?
Explicit memories are stored in the hippocampus, neocortex, and amygdala. Implicit memories are stored in the basal ganglia and cerebellum. Working memories are stored in the prefrontal cortex.
What is the role of the hippocampus when it comes to memory?
The hippocampus consolidates memory, holds long term memory, moves information between working and long term memory, and it records the information by strengthening the connections between specific neurons.
How can memory be improved?
Sleep, participating actively, practice, healthy diets, and exercise can help improve memory.
What do you remember the best?
You remember what you care about, what interests you, what you are emotional about.
what happens progressive memory disorders
Fatal brain disease, inability to acquire new memories, difficulty recalling recent facts
Which parts of the brain are involved with memory?
Working brain- prefrontal cortex, long term memory- Hippocampus, neocortex, and amygdala, nondeclarative- basal ganglia, cerebellum
What are immediate memory disorders?
Damage to the brain caused by an outside force, potential for amnesia, can be associated with memory impairment, disrupts normal brain functioning
Who is Henry Molaison?
Henry Molasions hippocampus was surgically removed, he could only store memories that lasted a few minutes, and they realized that the hippocampus was an important part for memories
1. Which part of the brain is each sense connected to?
Frontal Lobe-Smell, Pariental Lobe-Touch and Taste, Occipital Lobe-Vision, Temporal Lobe-Hearing
2. What are the five senses?
Sight, smell, hearing, taste, and touch
3. What sense is associated with the frontal lobe?
Your sense of smell
4. how do senses work
Sensory Neurons, which are neurons that receive sensory information for processing
5. are your memories and senses connected?
A familiar smell or sound might remind you of a past memory.
6. where are taste receptors
taste receptors are on the tongue and in the back of the mouth
7. How do sensations get to the brain?
Sensations get to the brain by sensory neurons.
8. Where does sight start?
starts in the retina
9. What portion of your cells is used in the cerebral cortex for sight
1/4 of your cells in the cerebral cortex are used
10. Why is keeping your senses in good shape important
So you can be well aware of your environment
11.One out of how many genes are dedicated to the sense of smell?
1 out of 50 genes
12. What is the first sense you use when you are born?
13. what is the connection between the 5 senses?
the 5 senses are connected through nerves, but literally speaking they are connected in context with our past experiences and information
14. Which is the last sense to develop?
