Chapter 48, Problem 8TYU
Summary Introduction
To explain: The effects of a drug on behavior that mimics the GABA in the central nervous system (CNS).
Introduction: Gamma aminobutyric acid (GABA) is an inhibitory neurotransmitter. It is involved in the communication between the brain cells.

QUESTION 22
Which one is not the best way to describe necessary "threshold" as "sensitivity" declines with age?
Individuals with lower sensitivity also have a lower threshold or tolerance for stimulation.
O
As sensitivity goes down, the threshold must be higher to compensate.
Individuals with a low-sensitivity, need more stimulation than people with high-sensitivity.
none of the above
QUESTION 23
Hi please help
The reward pathway is a neuronal pathway implicated in addiction to recreational drugs. Explain the role of the reward pathway in behaviour related to reward and motivation and discuss the anatomical regions and molecular and cellular pathways involved. Explain how the reward pathway is involved in drug addiction and give examples of experimental approaches that are being used to study drug addiction. Use figures and diagrams to illustrate your answer.

- Reward-modulated spike-timing dependent plasticity (RSTDP) can be modelled as STDP with an eligibility trace. RSTDP provides an explanation for how a reward that occurs a short time after the stimulus (i.e., outside the STDP learning window) can nevertheless cause a change in the synaptic strengths. The activities of two neurons, labelled A and B, are being recorded and are observed to have similar average spiking rates. Both neurons are observed to change their firing rates in response to both a stimulus and a reward. Describe how the timing of the delivery of the reward could be manipulated so that, during the learning period, the activity of neuron A increased but the activity of neuron B decreased.arrow_forwardWe know that short term habituation is due to changes in the presynaptic sensory neuron. What possible changes could explain the results of Kandel’s experiment? Which possibility currently has the most experimental support?arrow_forwardNeed help Different behavior patterns can be created by interactions of one or more pattern generators - in response to light touch, the sea slug, Tritonia, exhibits reflexive withdrawal of the body away from the stimulus (i.e. the sea slug “cringes”). However, a stronger mechanical stimulus induces the release of serotonin from specific neurons within the central nervous system and subsequent swimming behavior (i.e., an escape response). Both withdrawals of the body and swimming are driven by the same central pattern generator circuitry. This illustrates which important characteristic of central pattern generators? A. Model central pattern generators are not as complex as their real-world counterparts. B. Their rhythmic output is an emergent property of the neural network. C. Their output is not fixed but can be modifiedarrow_forward
