The AP exam in Computer Science was first offered in 1984. Before 1999, the AP exam tested students on their knowledge of Pascal. From 1999 to 2003, the exam tested students on their knowledge of C++ instead. Since 2003, the AP Computer Science exam has tested students on their knowledge of computer science through Java.
The glia limitans, or the glial limiting membrane, is a thin barrier of astrocyte foot processes associated with the parenchymal basal lamina surrounding the brain and spinal cord. It is the outermost layer of neural tissue , and among its responsibilities is the prevention of the over-migration of neurons and neuroglia , the supporting cells ...
The striatum (pl.: striata) or corpus striatum [5] is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. [6] The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.
The AP exam uses paper and pencil. (With the exception of year 2020, only Create and Explore were tested. In 2021, only Create and the multiple choice section were tested.) [7] It lasts 180 minutes and includes approximately 76 questions. The exam is composed of two sections: 74 Multiple-Choice Questions
A CT scan is the best test to look for bleeding in or around your brain. In some hospitals, a perfusion CT scan may be done to see where the blood is flowing and not flowing in your brain. Magnetic resonance imaging (MRI scan) : A special MRI technique ( diffusion MRI ) may show evidence of an ischemic stroke within minutes of symptom onset.

Consequently, the left side of the forebrain mostly represents the right side of the body, and the right side of the brain primarily represents the left side of the body. The contralateral organization involves both executive and sensory functions (e.g., a left-sided brain lesion may cause a right-sided hemiplegia).
Place cells may also show directionality, meaning they will only fire in a certain location when travelling in a particular direction. [8] [26] [27] An example of place cell remapping, with the location of the place field of cell 1 changing between environment, and cell 2 losing its place field in environment 2.
