Anterior, Lateral and Posterior Semicircular Canals, Utricle, Saccule and Cochlea 1 of 25 What are the Macula? Patches of hair cells inside each Otolith Organ. 2 of 25 The vestibular hair cells consist of a single tall hair called a what and a series of short hairs called what? Koniocilium; Stereocilium 3 of 25 The stereocilium and koniocilum are not quite mechanoreceptors in that... They release chemicals which hyperpolarises/depolarises the post synaptic cells, consequently sending a message to the 8th cranial nerve. 4 of 25 The semicircular canal has two facets in it called what, sensitive to what? The Christa (hair cells) and Capula (moved by fluid in the canal) 5 of 25 The fluid in the capula is called what? endolymph 6 of 25 What is retinal flow? movement of self through the environment 7 of 25 Complex tasks in multi sensory integration refer to what? Expansion of objects moving closer and lateral movement representing it getting closer. 8 of 25 Which brain cells are attuned to translational motion? MT 9 of 25 What is translational motion? something moving across the visual scene 10 of 25 Why can MT also detect expansion and contraction in motion? due to its connections with MST 11 of 25 Where is MT? In the temporal area 12 of 25 The Human Motion complex is made up of...? MT 13 of 25 Which areas respond to global flow/ patterns consistent with ego motion? Ventral Intraparietal Area/ Posterior Insula Cortex 14 of 25 What is global flow? Circular motion inconsistent with self motion, detected by Ventral Intraparietal Cortex & Posterior Insular Cortex 15 of 25 Yaw/Pitch/Roll results in..? Movement of fluid within the capula that pushes capula and sends information to the brain via the 8th Cranial Nerve. 16 of 25 The Cranial Nerves connect which parts of the Vestibular System? Vestibular Organs to Brain Stem. 17 of 25 Which canal operates the push pull system? Posterior Canal 18 of 25 The push pull systems inhibits the contralateral side to that that is stimulated. It also...? Triggers the ocular-motor reflex 19 of 25 The push pull system exists for the primary function of what? combining visual input to decipher what is related to self motion and what is related to exterior motion. 20 of 25 What is the Torsional Ocular Reflex? Tilting your head to the right will result in the eyes moving to the left, and vice versa. 21 of 25 Single cell recordings indicate what with regards to cancelling head motion? specific cells in the dorsal stream network can detect congruent/incongruent motion RE the self and the environment 22 of 25 Which areas of the dorsal stream network are specifically concerned with cancelling motion? Dorsal Medial superior Temporal area (MSTd) and Ventral Intra Parietal (VIP 23 of 25 In humans, what studies can be used to detect patterns of activation? MRI & GVS 24 of 25 What is GVS? Galvanic Vestibular Stimulation: stimulates vestibular organs to induce feeling of head roll. 25 of 25
