BRAIN MAPPING IN NEUROSURGERY
Background and Aim: Brain mapping is a study of the anatomy and function of the CNS (central nervous system). Brain mapping has many techniques and these techniques are permanently changing and updating. From the beginning, brain mapping was invasive and for brain mapping, electrical stimulation of the exposed brain was needed. However, nowadays brain mapping does not require electrical stimula...
متن کاملAcoustically evoked potentials in the rat during conditioning.
Acoustically evoked potentials were recorded from unanesthetized rats in a series of experiments designed to study changes in sensory evoked potentials during conditioning. It is shown that when clicks a re established as conditional stimuli (CS) in conditioned emotional response (CER) situations , click-evoked potentials recorded from central auditory structures and from mesencephalic reticula...
متن کاملBrain mapping of visual evoked activity--topographical and functional components.
Electroencephalographic (EEG) and evoked activity can be recorded non-invasively in order to monitor human brain activation online. Electrical fields are generated by large intracranial neural populations and spread to the scalp through volume conduction. All measured signals depend on the location of the recording and reference electrodes. Simultaneous recordings from many scalp positions allo...
متن کاملMapping human brain networks with cortico-cortical evoked potentials.
The cerebral cortex forms a sheet of neurons organized into a network of interconnected modules that is highly expanded in humans and presumably enables our most refined sensory and cognitive abilities. The links of this network form a fundamental aspect of its organization, and a great deal of research is focusing on understanding how information flows within and between different regions. How...
متن کاملBrain mapping in Neurosurgical oncology
After the introduction of MRI, new modalities facilitated the procedure of surgical planning to achieve the microsurgical goal and improve prognosis and quality of life in patients. Despite the variable applications of preoperative and intraoperative mapping and monitoring systems, several limitations and concerns are reported for every modality as well. In this issue of the IrJNS, we are delig...
