[The influence of stimulation dopaminergic D, i D2 receptors in lateral geniculate body on flash visual evoked potentials (FVEP) in rats].

Purpose: The topic of this paper is to define the influence of stimulation dopaminergic D1 i D2 receptors in lateral geniculate body by flash visual evoked potentials (FVEP).

Material And Methods: Wistar rats were examined. There were stereotaxically implanted with guide caniula into the lateral geniculate body to inject substances and with VEPs electrodes on the skull and on the surface of visual cortex.

[The influence of dopamine injected into the lateral geniculate body on flash visual evoked response in rats].

Purpose: Numerous neurotransmitters and neuromodulators operating on all levels of the visual system, influence the parameters of cortical evoked response. The aim of this study was to find the influence of dopamine (DA) injected into the lateral geniculate body (nucleus) on flash visual evoked response (FVEP).

Material And Methods: The experiments were performed on adult Wistar rats.

[The function of eye and vision system in children and youth treated with vigabatrin--our own experiences].

Purpose: The aim of this study is to find the relationship between visual function changes and vigabatrin treatment continuation or discontinuation.

Material And Methods: 19 patients (11 males, 8 females) from 8 to 20 years old, treated with vigabatrin because of partial epilepsy, were examined. Best corrected visual acuity, contrast sensitivity and static visual field were done.

[Visual evoked potentials (FVEP) after the prenatal exposure to heavy metals--experimentals studies].

Purpose: To find out, if any and how deep alterations in visual tract are due to prenatal intoxication by heavy metals such as: cadmium (Cd), lead (Pb), mercury (Hg) and manganese (Mn). The measure of these alterations were the changes in flash visual evoked potentials after prenatal intoxication.

Material And Methods: The experiments were carried out on 55 white newborns Wistar rats, which were divided into 5 groups: control group (14 rats), Cd group (12), Pb (6), Hg (14) and Mn (9).
