long term potentiation
the pre and posy synaptic neuron will be regular coactivated and thus strengthen the neural pathway, making the skills more efficient. this occurs because sprouting occurs where dendrites become more buisher. increased amont of receptor sitres of post synaptic neuron. thus increased amount of synaptic connections due to sprouting
long term depression
the pre and psot synaptic neuron will not get regulary coactivated nad thus weaken the synaptic connection making it the skill ineffieceint. allowing new things to learn. decreased amount of receptor sites of post synaptic neuron, and thus decreased amoutn of synaptic connections
spinal reflex - unconscious repsonse
the stimulus is deteced by sensory receptors wihch sends a message via sensory neurons to the spinal cord. the interneuron in the spinal cord immediately relays this sensory signal to a motor neuron which turns it into a motor message. initiating an automatic and unconscious motor response. the motor message is sent to the skeletal muscles via motor neurons to carry out this unconscious motor response to the stimulus
conscious response
the stimulus is detected by sensory receptors which sends a sensory message through the afferent pathway and then the spinal cord to the brain. the brain processes this sensory information, coordinating and initiating a conscious motor response. the motor message is sent via the efferent pathway in the spinal cord and to the somatic ns to skeletal muscles. in which the skeletal muscles will carry out the conscious response to the stimulus.
acute response to stress for fight and slight
hypothalamus activates sympathetic nervous system which stimulates the adrenal glands and secrete adrenaline adn noradrenaline.
then in chronic stress in flight and fight
the hypothalamus then stimulates the pituitary glan which releases hormones to stimulate the adrenal glans to secrete cortisol
HPA AXIS
define mixed design
combines elements of between subject design and within subjects design. as tehy comparae between groups adn within groups
