Cortical neurons related to lens accommodation in posterior lateral suprasylvian area in cats. 1984

T Bando, and N Yamamoto, and N Tsukahara

Cortical units were sought that discharged in temporal correlation with spontaneously occurring lens accommodation in the area surrounding the middle suprasylvian sulcus, between the stereotaxic coordinates A8.0 and P1.0, while monitoring lens accommodation by using an infrared optometer. Units were tentatively identified as accommodation related if their discharges were modulated before the onset times of lens accommodation. Forty-eight accommodation-related units were found. Modulation of discharges preceded the onset times of accommodation by 360 ms on the average. Most (95%) of these units were related to the increase in the refractive power of the lens. Antidromic activation from the dorsal midbrain was tested in 26 of 48 accommodation-related units. Fourteen (67%) units were antidromically activated from the superior colliculus and/or the pretectum. Nine (64%) of them were also activated antidromically from the lateral posterior nucleus of the thalamus. The location of these units were confirmed by histological reconstruction. They were found in the posterior medial and posterior lateral lateral suprasylvian (PMLS and PLLS) areas and in the transitional zone of PMLS to the suprasylvian gyrus, between stereotaxic coordinates A7.0 and A1.5.

D007908	Lens, Crystalline	A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.	Eye Lens,Lens, Eye,Crystalline Lens

D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D005071	Evoked Potentials	Electrical responses recorded from nerve, muscle, SENSORY RECEPTOR, or area of the CENTRAL NERVOUS SYSTEM following stimulation. They range from less than a microvolt to several microvolts. The evoked potential can be auditory (EVOKED POTENTIALS, AUDITORY), somatosensory (EVOKED POTENTIALS, SOMATOSENSORY), visual (EVOKED POTENTIALS, VISUAL), or motor (EVOKED POTENTIALS, MOTOR), or other modalities that have been reported.

D000065	Accommodation, Ocular	The dioptric adjustment of the EYE (to attain maximal sharpness of retinal imagery for an object of regard) referring to the ability, to the mechanism, or to the process. Ocular accommodation is the effecting of refractive changes by changes in the shape of the CRYSTALLINE LENS. Loosely, it refers to ocular adjustments for VISION, OCULAR at various distances.
