Emotions

Emotions are biologically based psychological conditions caused by neurophysiological changes which are linked to different factors such as thoughts, emotions, behavioral responses, and pleasure or displeasure. These emotions are not similar to moods. The mood is an affective state. Mood depends upon several factors, such as weather, the environment, physiology, etc. Emotions can be beneficial or detrimental depending on the situation. Emotional reactions are simple. Emotional well-being is strongly affected by our well-being, and such feelings are private.

Larry goes to the doctor complaining that he cant see the right side of the visual field with either eye. Where in the visual signal-processing pathway is Larrys problem occurring?
We compared the speed of transduction of the taste of sour vs either sweet or bitter, depending on what you tasted. Match the taste modality to the most likely transduction mechanism: Ion channel or second messenger system based on what is known. Salty is left out because there is not enough known about it. Sour Bitter Sweet Umami
Do gustatory taste cells have BOTH chemoreceptors and mechanoreceptors? The chemoreceptors are responsible for receiving the signals that the saliva molecules send via action potentials, but there are also hair cells attached to the taste cells that detect movement?
what statement/s is true about Neuronal Pathways for Olfaction a. Axons from the olfactory neurons extend as olfactory nerves to the olfactory bulb, where they synapse with mitral and tufted cells. b. The olfactory bulb neurons can modulate output to the olfactory tracts. c. The olfactory tracts terminate in the sensory and temporal cortex. = sensory should be olfactory d. The lateral olfactory area is involved in the conscious perception of smell, the intermediate area with modulating smell, and the medial area with visceral and emotional responses to smell.
In the sensory pathway for taste The second order neurons go to the limbic system Taste information is carried by the facial, glossopharyngeal, and vagus cranial nerves All of these are correct The receptor cells are the first–order neurons
We discussed three principles with regards to the sensory cortex (mechanisms of perception), with one of them being a hierarchical organization. Using the somatosensory system as an example (specifically the exteroceptive part of that system), state each level of the hierarchy with regards to this system, beginning with the one at the lowest level of the hierarchy to the final uppermost level. give the name at each level as it corresponds with this system.
The area in the anterior portion of the temporal lobe that receives input from the olfactory bulb and is often considered to be the primary olfactory cortex is the ______. Question 49 options: parietal cortex entorhinal cortex piriform cortex cerebral cortex Small structures located along the surface of the tongue or mouth that contain the receptor cells for taste are called ______. Question 13 options: taste buds gustatory papillae circumvallate papillae turbinate fibers
A patient has had a stroke that damaged the trigeminal nerve but not the facial, glossopharyngeal, or vagus nerve. Would this individual still be able to taste the differenceWould this individual still be able to taste the difference between hot peppers and French fries? Explain your answer.
The first relay in the brain for nerves carrying taste information is: a. the cerebral cortex b. the hypothalamus c. the orbital prefrontal cortex d. the nucleus of the solitary tract A single action potential in a somatic motoneuron produces a twitch in the muscle it innervates. Generation of sustained contraction is a product of that motoneuron producing multiple action potentials. What is a term used to describe this phenomenon? a. Stretch reflex b. Temporal summation c. Spatial summation d. Muscle fatigue
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?
Which of the following happens in taste receptor cells when the membrane is depolarized by a receptor potential? a. Voltage-gated Ca?+ channels open, triggering the release of neurotransmitter. b. Voltage gated K+ channels open, triggering the release of neurotransmitter. c. Voltage-gated Ca?+ channels open, inhibiting the release of neurotransmitter. d. Voltage gated K+ channels open, inhibiting the release of neurotransmitter. e. Cyclic nucleotide gated ion channels open, increasing the release of neurotransmitter.
