Sentences with word «tectum»

Investigating the effects of sex steroids in the optic tectum in common goldfish, Carassius auratus.

Visual pathways to thalamus and tectum do not participate in this response.

Two - photon calcium imaging of retino - recipient midbrain regions isolated the optic tectum as an important center processing looming stimuli, with ensemble activity encoding the critical image size determining escape latency.

Felice Chan: Investigating sex steroid hormone effects in the optic tectum using the visual system of the common goldfish (Carassius auratus)(Advisor: L. Wilson)

Ualberta engineering admission essay marked language essays online dating research paper conclusion apa tectum verlag dissertation abstracts.

In January, Knudsen's team discovered that a brain area called the optic tectum (OT) sends visual signals that tweak the map: When the team members destroyed the connections between the OT and ICX, the map ceased adjusting.

They also had a larger «optic tectum», which processes visual stimuli and could be related to the need to process more visual stimuli in larger groups, say researchers.

To conduct the study, Aizenman's group reared tadpoles in the lab, exposing some to VPA during the key window of time for development of the optic tectum, a critical part of the brain for sensory processing.

James saw several key anatomical differences in the optic tectum.

The dendrites of VPA - exposed tadpoles grew and branched abnormally according to his measurements, perhaps reflecting differences in how the tectum circuits were becoming wired during the VPA - exposed development.

Many of these core structures are still found in our brains: the optic tectum, involved in tracking moving objects with the eyes; the amygdala, which helps us respond to fearful situations; parts of the limbic system, which gives us feelings of reward and helps to lay down memories; and the basal ganglia, which control patterns of movements.

When DiI was applied to the RGC layer of induced eyes, labeled processes were observed projecting dorsocaudally along the spinal cord away from the tectum (unpublished data).

They show that a gradient of Wnt3 along the medial - lateral axis within the developing brain is the opposing regulating force — working along with ephrinB1 to specify the topographic target selection in the optic tectum, a brain region that processes information from the eye.

They performed an electrophysiological analysis of each tadpole's optic tectum, a part of the brain responsible for processing visual information.

Furthermore, we describe activity in retinal ganglion cell terminals and superficial inhibitory interneurons in the tectum during looming and propose a model for how temporal dynamics in tectal periventricular neurons might arise from com - putations between these two fundamental constitu - ents.
