From a biological perspective, how does our sense of smell work? Discuss the concept that our sense of smell is directly connected to the brain. Include a relevant example. Please include references.

Put the following events in order beginning with the event that happens first in order for one to have the sense of sight: ___Light passes through the pupil. ___Rods and/or cones initiate nerve impulses. ___Nerve impulses are carried to the brain by the optic nerve. ___Light passes through the cornea. ___Light passes through the anterior chamber of the anterior cavity. ___Light passes through the posterior chamber of the anterior cavity. ___Impulses reach the occipital lobe of the cerebrum. ___Light passes through the vitreous humor. ___Light passes through the lens. ___Light hits light sensitive pigments in photoreceptors

Electronic pest control is the name given to several types of electrically powered devices designed to repel pests, such as insects. Ultrasonic devices have shown promise in repelling insect pest species. They emit short wavelength, high-frequency sound waves that can be detected by insects but are too high-pitched to be detected by humans. The following table shows the maximum end of the hearing range of frequencies detectable by various organisms (Table 1). To investigate the effectiveness of ultrasonic devices in dispersing pest insects, scientists collected data from two different regions. Region 1: a rural crop-growing region where insecticides are applied for crop protection Region 2: a protected nature reserve that is managed for conservation and researchScientists measured the population density of insects in both regions before and after activating two different kinds of ultrasonic devices. The first ultrasonic device emitted sound at a frequency of 40 kHz and the second…

Imagine you wake up to the smell of smoke, The sound of the fire alarm, the flashing lights of sirens, the acreage taste of smoke in the air. In other words, all your senses are reacting to this emergency. Your body goes into "flight or fight mode".  Question: in about two paragraphs, can you describe the sensory pathway that the sensory information from just one of these special senses takes to the brain to be integrated. for example, if you were describing the smell of the smoke, how was odor detected? Which cranial nerves are involved? Where are those located? Where do they connect to the rest of the brain?

Here you see an astigmatism illustration. Please explain why astigmatisms cause blurred vision in the context of our sense of sight. Please do not merely say “The light rays do not hit the focal point”. Please explain why that matters for the sense of sight.

Receptors within the olfactory epithelium in the nasal cavity project to the glomeruli, which project to the mitral cells, which project as cranial nerve one to the pyriform and the entorhinal cortex located in the anterior and medial temporal lobe. What's odd about this sensory pathway, unlike other sensory pathways? Select one: a. it does not show sensory adaptation b. there is no thalamic nuclei processing olfactory infomation prior to processing in the primary cortex c. loss of smell can be a result of damage to the temporal lobe or damage to the olfactory receptor cells d. it processes information ipsilaterally e. the primary olfactory cortex is not part of the telencephalon

The lateral geniculate nuclei (LGN)are 6-layer structures in each hemisphere, which receive input from the retina from the ipsilateral and contralateral eyes. What is true of the layer distribution of the LGN regarding how they receive inputs from the eyes? layers 1, 4 and 6 from contralateral eye layers 4,5 and 6 from ipsilateral eye layers 2,3 and 5 from ipsilateral eye a) and c)

Transforming visual input into motor output involves ______and______ 1. dorsal premotor area for reaching; supplementary motor area for grasping 2. supplementary motor area for reaching; ventral premotor area for grasping 3. supplementary premotor area for grasping; ventral premotor area for reaching 4. dorsal premotor area for reaching; ventral premotor area for grasping 5. dorsal premotor area for grasping; ventral premotor area for reaching

Provide a step by step list of visual sensation through visual processing. Begin at light entering the eye through signal transduction, to the circuitry involved in the brain in understanding the "what" and "where" of the object. Be sure to review the specific criteria outlined in the rubric.

What differentiates the temporal aspects of the human visual system from its optical properties?
