To draw: The three touch receptors having overlapping receptive fields.
Introduction: There are five different sensory organs found in the body, namely skin, tongue, eyes, ear, and nose. Out of these five sensory organs, the neurons present in the skin also called as somatic neurons and the neurons associated with vision get activated as a result of the stimuli that fall on a particular region of the body called as receptive field.
To determine: The different regions that the brain can identify on the basis of input from the three receptors.
Introduction: The somatic neurons are responsible for collecting information from the receptor cells and convert the signal to the electrical or chemical signal and transmit it to the interneurons present in the spinal cord.

- 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?arrow_forwardWhat does your map of cutaneous sensations tell you about the distribution of sensory receptors in the skin?arrow_forwardDraw a simple (typical of somatic senses) and a complex (typical of special senses) sensory neuron (receptor). Where applicable, label the cell body, the axon, the nerve endings, myelin, and the axon terminal.arrow_forward
- A scientist has dissected out a small section of the retina and is able to directly record the action potential firing rate in a single ganglion cell. Assume there is a on-center off-surround bipolar cell connected to an on-center off-surround ganglion cell. When applying ‘Stimulus 1’ the scientist records a moderate action potential rate. When applying ‘Stimulus 2’ the rate of action potentials increases substantially. In the context of this experiment no illumination is an option as a 'Stimulus'. ‘Stimulus 2’ would result in what response in the bipolar cell (the one connected to the ganglion cell the scientist is measuring)? A. A large depolarization of the bipolar cell membrane B. The bipolar cell membrane would remain at the resting membrane potential C. A large hyperpolarization of the bipolar cell membrane D. A small hyperpolarization of the bipolar cell membrane E. A small depolarization of the bipolar cell membranearrow_forwardAn 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 be withdrawn through a reflex arc. How do we sense different types of pain (very painful vs. not painful at all)? Using your knowledge of threshold potential and the all-or-none principle, explain how it is possible to sense different levels of pain.arrow_forwardIn general, could we name the sensory receptors “middle men” between the stimulus and the peripheral nervous system? Please shortly explain your answer.arrow_forward
- Identify, in correct order, of sensation to perception, the major connections of the pathway underlying fine touch, and pressure. afferent axons decussate at medulla primary somatosensory cortex activated somatosensory humunculus according to where on body touch was felt free nerve endings depolarize dendrites of peripheral afferents axons in the medial lemniscus terminate in the ventral posterior nucleus of the thalamus axons of afferents enter into dorsal horn of spinal cord and ascend ipsilaterallyarrow_forwardSelect all of the statements that are true about gustation: The papillae on the tongue are the receptor cells for taste molecule stimuli. Salt and sour taste stimuli sense Na+ ions and H+ ions respectively. In order for sweet tastes to be sensed, the taste molecule must first bind to a protein receptor in a taste bud. The gustatory pathway for the processing of taste stimuli are relayed to the thalamus, and then to the gustatory cortex for processing by the brain.arrow_forwardWe 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.arrow_forward

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 boldarrow_forwarda) Based upon how the neural membrane functions, briefly explain how electrical stimulation can cause a neuron to generate an action potential. Describe in one sentence a type of action potential that can be generated by electrical stimulation, but that cannot be generated by synaptic inputs. b) The central part of the retina consists largely of cones, which are responsible for colour vision in normal sight. However, presently available retinal prostheses are not able to reliably provide a perception of colour for people implanted with these devices. Explain why people with a retinal prosthesis are currently unable to reliably perceive colour.arrow_forwardDescribe each of the following types of receptors, indicating what sensation it detects and giving an example of where it can be found in the body: pain receptors (nociceptors), temperature receptors,mechanoreceptors (including proprioceptors and barorceptors/pressoreceptors), chemoreceptors, and photoreceptors.arrow_forward
