Summary
| Description |
English: Tectal prey feature detectors T5.2 project the axons towards bulbar premotor/motor systems. Their response characteristic results from integration in a neuronal network involving retinal gangion cells R2, R3, R4, pretectal thalamic neurons TH3, and tectal neurons T5.1, T5.3. Arrows: excitatory connections; lines with terminal dots: inhibitory influences. Connections were checked, e.g., by means of intracellular recording postsynaptic potentials, horseradishperoxidase or cobalt-lysine tracing, antidromic electro-stimulation/recording, neurochemical techniques, chemical lesions by kainic acid. Hypothesis after Ewert 1974 and 2004 Deutsch: Tectale Beutemerkmal-Detektoren T5.2 projizieren zu medullären Praemotor/Motor-Systemen. Ihre Antwortcharakteristik resultiert aus der Integration in einem neuronalen Netzwerk unter Beteiligung von retinalen Ganglienzellen R2, R3, R4, praetectal thalamischen Neuronen TH3 und tectalen Neuronen T5.1, T5.3. Pfeile: erregende Verbindungen; Linien mit terminalen Punkten: hemmende Einflüsse. Verbindungen wurden überprüft mit Hilfe von intrazellulär abgeleiteten postsynaptischen Potentialen, Faserveraufsverfolgung unter Verwendung von Meerrettichperoxidase oder Cobalt-Lysin, antidromer Elektrostimulation/Ableitungs-Technik, neurochemischer Methodik, chemischen Läsionen mittels Kainsäure. Hypothese nach 1974 und Ewert 2004 |
