Psychoactive Drugs
What kind of drug is meth?
Meth is a stimulant
What is the function of the frontal lobe?
The frontal lobe is responsible for planning, decision making, and all cognitive abilities.
What is the limbic system?
The structure and the parts that make up the limbic system are involved in motivation, emotion, learning, and memory. The limbic system is where the subcortical structures meet the cerebral cortex. The system contains the amygdala, hypothalamus, hippocampus, and the thalamus.
What is the hindbrain?
The hindbrain coordinates functions that are fundamental to survival, including respiratory rhythm, motor activity, sleep, as well as wakefulness. The hindbrain includes the pons, spinal cord, medulla, and Cerebellum
What occurs during light sleep?
Alpha waves in the brain decrease as theta waves increase, breathing begins to slow, and twitching can occur.
What kind of dug is alcohol?
Alcohol is a depressant
What is the function of the parietal lobe?
The parietal lobe controls sense and touch, and pain.
What is the thalamus responsible for?
The thalamus relays sensory impulses from the receptors in various parts of the body to the cerebral cortex. A sensory impulse travels from the body surface towards the thalamus, which receives it as a sensation. It is then passed onto the cerebral cortex for interpretation as touch, pain, or temperature. The main function is to relay sensory and motor signals as well as the regulation of consciousness and alertness.
What is the function of the cerebellum?
The cerebellum is important for our ability to learn and perform skilled movements.
What happens during sleep spindles?
The brain wave cycle begins to slow, sleepwalking and sleepwalking can occur, this lasts about 20 minutes usually.
What kind of drug is lsd?
LSD is a hallucinogen.
What is the function of the temporal lobe?
Processes the sound of information from the ears. Controls what you hear.
What is the hypothalamus for in the limbic system?
A very small part of the brain that is located at the base of the pituitary gland, Although its small the hypothalamus plays a crucial role in many important functions such as releasing hormones, regulation body temperature, maintaining daily physiological cycles, controlling appetite, and managing our sexual behavior.
What is the medulla oblongata?
Medulla oblongata- is the lower half of the brainstem. The medulla is responsible for regulation several basic functions of our autonomic nervous system. It transfers messages to the spinal cord as well as the thalamus to process information. It has several basic functions of the autonomic nervous system, including respiration, cardiac functions, vasodilation, and reflexes including vomiting, coughing, sneezing, and swallowing.
What occurs in the first wave of deep sleep?
This only lasts a few minuets before entering the second stage. Large slow delta waves begin to slow.
What kind of drug is heroin?
Heroin is a depressant.
What is the function of the occipital lobe?
The occipital lobe is responsible for controlling what you can see, contains visual cortex.
What is the main function of the hippocampus?
Hippocampus- is responsible for playing roles in the consolidation of information from short-term and long-term memory. It is also crucial in helping link our memory to navigation. This ‘part’ of the brain can help you remember something important.
What are the pons main function?
Pons- pons relay sensory information to our cerebellum as well as help us regulate our own breathing. Pons assist in control of sleep cycles. The pons connects the forebrain to the hindbrain.
What occurs during the second wave of deep sleep?
Growth hormones are released throughout the body as the second wave of deep sleep begins. This usually lasts around 30 minuets.
what kind of drug is nicotine?
Nicotine is a stimulant.
What is the function of the cerebral cortex?
This is the utter layer of the cerebrum, composed of grey matter and this part of the brain plays a big role in consciousness.
What is the Amygdala and what are its functions?
The amygdala is located close to the hippocampus, in the frontal position of the temporal lobe. Your amygdala is responsible for emotions such as anger, fear, and sadness, as well as being able to control aggression. It also stores memories of events and emotions that that an individual may be able to recognize similar events in the future.
What is the function of the brain stem?
The brain stem controls the flow of messages between the brain and the rest of the body, yet it also controls our basic body functions such as breathing, swallowing, heart rate, blood pressure, consciousness, and whether or not one is sleepy or awake.
What is REM sleep?
Rem sleep occurs when your body resembles beta waves. Body temperature and heart rate increase. Most dreams take place during REM sleep.
