What is the action of the neurotransmitter that is released from photoreceptor cells on bipolar cells?
In most neurons, membrane depolarization leads to the opening of voltage-dependent ion channels, generation of an action potential, and, ultimately, an influx of Ca2+, which causes release of neurotransmitter at the axon terminus. Devise a cellular strategy by which hyperpolarization in rod cells could produce excitation of the visual pathway and passage of visual signals to the brain. (Hint: The neuronal signaling pathway in higher organisms consists of a series of neurons that relay information to the brain. The signal released by one neuron can be either excitatory or inhibitory to the following, postsynaptic neuron.)
Cascading effect occurs when a signal is receive by the receptor ( " turned on" ) but how do cells turns off a signal?
If TTX (tetrodotoxin) selectively binds voltage gated Na+ channels, and you tag TTX with a fluorescent marker and then you use it as a probe to label voltage-gated Na+ channels in various neurons in the CNS, would you expect the pattern of fluorescence to be different between myelinated and nonmyelinated axons? If so, how? If not, why not?

Color vision is trichromatic in that 3 primary colors can mix and match all other colors. However, there are 4 unique colors or hues that come in opponent pairs. Name and describe what retinal elements or structures produce trichromacy, compared to what retinal elements or structures produce unique color signals and opponent color pairs?
Do you know why the membrane of a neuron is polarised?
During phototransduction, the molecular processing in retinal rods under light activates mechanism to reduce cGMP that hyperpolarizes the cell. The correct sequence of cellular events is: activation of 11-cis-retinal --> activation of Transducin---> enzyme degrades CGMP activation of Transducin --> opening of Na+ channel --> hyperpolarization of cell activation of Transducin --> a photon induces 11-trans-retinal --> enzyme degrades CGMP 0 a photon induces 11-transretinal activation --> closing of Na+ channel --> hyperpolarization of cell
