An in-class test of the opponent process theory of color vision relied on a basic principle of neurophysiology to explain color afterimages. What is this basic principle? O If a cell is excited or inhibited for a long period of time by a strong stimulus, when the stimulus is terminated the cell will temporarily "undershoot" or "overshoot" its normal activity rate. Receptor cells are able to respond to a wide variety of sensory inputs, but sensory neurons are only able to respond to a select few types of inputs. Sensory receptors are the first cells to process incoming stimuli, while sensory neurons have to rely on input from receptors in order to function. Retinal ganglion cells act in a non-intuitive "opposite" fashion, being inhibited by a strong stimulus, but excited by a weak stimulus.

Certain cells in the retina respond differently to the direction in which objects move. To understand how cells in the retina respond to different visual stimuli, the activity of a retinal ganglion cell was measured while a square moved across its visual field. Which statement best explains the increases in voltage during the periodic spikes? A. Depolarization of a neuron past a threshold voltage causes sodium channels to close. B. Depolarization of a neuron past a threshold voltage causes sodium channels to open. C. Depolarization of a neuron past a threshold voltage causes potassium channels to close. D. Depolarization of a neuron past a threshold voltage causes potassium channels to open.
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.

Receptor cells that are neurons with sensory dendrites are faster than receptor cells that are separate from neurons. Why is that, and why might that be important in, for example, the sense of touch versus vision?
An example of a sensory neuron is one that leads from a pain receptor in the finger to the spinal cord. A pin can be pressed against the skin without eliciting a response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly withdrawn through a reflex arc. How do we sense different types of pain (very painful vs. not painful at all)? Using what you understand about threshold potentials and the all-or-none principle, explain how it is possible to sense different levels of pain. question is in bold
In complete darkness, why are there no neural signals being sent to the brain by the retinal ganglion cells? A. glutamate release from rods stimulates the retinal ganglion cells B. glutamate release from rods stimulates bipolar cells which then inhibit retinal ganglion cells C. glutamate release from rods is reduced which then fails to excite retinal ganglion cells D. glutamate release from rods inhibits the bipolar cells which then inhibit retinal ganglion cells
Caffeine is an inhibitor of the enzyme phosphodiesterase. Predict what caffeine will do to my heart rate -- Support with the correct physiological mechanism And you may ask yourself "Well....how did I get to membrane potentials?" If caffeine were applied to the retina, what would happen. Include the mechanism we covered on how you detect light
Receptor potential generates :-a- an electrotonic current which is transmitted along sensory fibers to the CNSb- a nerve impulse at the receptive region of the receptorc- a state of hyperpolarization of the receptor membraned- a nerve impulse at the spike initiating region of the receptor
Our brain receives more action potentials when our eyes are exposed to light even though our photoreceptors release more neurotransmitter in the dark. Propose an explanation.
If light strikes only one receptor, what is the net effect (excitatory or inhibitory) on the nearest bipolar cell that is directly connected to that receptor? What is the effect on bipolar cells to the sides? What causes that effect?
A pin can be pressed against the skin lightly and elicit no response from the pain receptor how ever, if this pain is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc. use what you know about threeshold potential and the all-or-none principle to explain different levels of sensation (light touch or pain)
