Xochitecatl [ʃot͡ʃiˈtekat͡ɬ] is a pre-Columbian archaeological site located in the Mexican State of Tlaxcala, 18 km southwest of Tlaxcala city. [1] The major architecture dates to the Middle Preclassic Period (1000–400 BC) but occupation continued, with one major interruption, until the Late Classic , when the site was abandoned.
Cacaxtla (Nahuatl pronunciation: [kaˈkaʃtɬaːn]) is an archaeological site located near the southern border of the Mexican state of Tlaxcala. It contains a sprawling palace with vibrantly colored murals painted in Maya style. The nearby site of Xochitecatl was a more public ceremonial complex associated with Cacaxtla.
With its medial boundary corresponding approximately to the rhinal sulcus it is located primarily in the fusiform gyrus.Cytoarchitecturally it is bounded laterally and caudally by the inferior temporal area 20, medially by the area 35 and rostrally by the temporopolar area 38 (H) (Brodmann-1909).
In neuroanatomy, the pretectal area, or pretectum, is a midbrain structure composed of seven nuclei and comprises part of the subcortical visual system.Through reciprocal bilateral projections from the retina, it is involved primarily in mediating behavioral responses to acute changes in ambient light such as the pupillary light reflex, the optokinetic reflex, and temporary changes to the ...
The retrosplenial cortex (RSC) is a cortical area in the brain comprising Brodmann areas 29 and 30. [1] It is secondary association cortex, making connections with numerous other brain regions. The region's name refers to its anatomical location immediately behind the splenium of the corpus callosum in primates, although in rodents it is ...
Brodmann area 38, also BA38 or temporopolar area 38 (H), is part of the temporal cortex in the human brain. BA 38 is at the anterior end of the temporal lobe, known as the temporal pole. BA38 is a subdivision of the cytoarchitecturally defined temporal region of cerebral cortex.
The optic chiasm is found in all vertebrates, although in cyclostomes (lampreys and hagfishes), it is located within the brain. [ 2 ] [ 3 ] This article is about the optic chiasm of vertebrates, which is the best known nerve chiasm, but not every chiasm denotes a crossing of the body midline (e.g., in some invertebrates , see Chiasm (anatomy) ).
The subject's task is to make a saccade to the location of the target. Neurons in area LIP have been shown to start responding with the initial presentation of the stimulus. The neurons keep responding through the delay period until the saccadic eye movement starts and the animal soon focuses on the exact location of the previously shown target.
