The brain’s somatosensory cortex does not consist of neurons that receive information equally from all parts of the animal’s body. Describe an example of this by identifying a relevant animal and the body parts that are disproportionately high in neuronal input to the somatosensory cortex.

List the general sequence of events that occur in the nervous system from the time you see the ruler drop to the time you catch the ruler. List each of the nervous system structures involved, including each brain area used in this process. Start with the photoreceptors and end with the muscles in your forearm and fingers.

Describe the 5 basic steps of electrical and chemical neural signaling.  A strong action will explain each step.  Also, describe at least one way synaptic connections can change as a result of experience or learning.

Explain a way that sensory nervous system transduce stimuli with different strengths using concept of action potential frequency

Which of the following provides the most accurate example of active sensing being used by an animal? Male moths use paired antenna to track the pheronome trail of a female moth Electric fish detect the electric field of other nearby electric fish Cats have a tapetum that enhances their night vision for hunting prey in the dark Bats use echolocation to hunt flying insects at night

This is a type of signal in the brain that changes when we do an action/movement or when we see someone else do an action/movement:

Sense of smell, also known as olfaction, is the ability to perceive and interpret odours. When a chemical molecule interacts with an odour-receptor protein located on the sensory neuron in the nose, an action potential is triggered and sent along the axon. The interaction between a chemical molecule and an odour-receptor protein will first initiate the movement of _____A______ ______B_____ the _____C______ of the _____D_____ neuron. Using the numbers given below, identify A to D. A B C D Chlorine ions Potassium ions Sodium ions Into Out of Axon Dendrite Axon terminal Nodes of Ranvier Interneuron Motor neuron Sensory neuron A: AnswerB: AnswerC: AnswerD: Answer
