This presentation on drugs and disorders of the nervous system delves into how various substances interact with synapses to modify brain function. It explains that drugs, whether taken for medical or recreational purposes, alter chemical reactions by affecting neurotransmitter diffusion. Stimulants increase the release of neurotransmitters, enhancing neural activity, while depressants inhibit signal transmission by blocking receptor sites. The presentation also covers the classification of drugs, noting the legal distinctions—ranging from Class A, the most dangerous, to Class C, which carry lighter penalties.
