AND THERAPEUTIC INTERVENTIONS
◉ Messenger RNA Synthesis. Answer: The process of transcribing a
segment of DNA into RNA, which then carries the genetic
information to the ribosome for protein synthesis.
◉ Translation into Protein. Answer: The process by which
ribosomes synthesize proteins using the information carried by
messenger RNA.
◉ Mutations. Answer: Changes in the DNA sequence that can affect
gene function and lead to various disorders.
◉ Clinical Psychopharmacology. Answer: The study of the use of
medications in treating mental disorders.
◉ Neurotransmitters. Answer: Chemical messengers that transmit
signals across synapses from one neuron to another.
,◉ Biogenic Amine Neurotransmitter Nuclei. Answer: Clusters of
neurons in the brain that produce biogenic amine neurotransmitters
such as serotonin and dopamine.
◉ Glutamate. Answer: The most abundant excitatory
neurotransmitter in the brain, playing a key role in synaptic
plasticity and cognitive functions.
◉ γ-Aminobutyric Acid (GABA). Answer: The primary inhibitory
neurotransmitter in the brain, which helps to regulate neuronal
excitability.
◉ Monoamine Neurotransmitters. Answer: A group of
neurotransmitters that includes serotonin, dopamine,
norepinephrine, and epinephrine, involved in regulating mood and
emotional responses.
◉ Histamine. Answer: A neurotransmitter involved in immune
responses and regulating physiological functions in the gut.
◉ Acetylcholine. Answer: A neurotransmitter that plays a role in
muscle activation and is involved in learning and memory.
,◉ Peptide Neurotransmitters. Answer: Neurotransmitters composed
of amino acids, such as endorphins and enkephalins, which
modulate pain and stress responses.
◉ Neuroimaging Techniques. Answer: Methods used to visualize the
structure and function of the brain, including MRI, CT, MRS, SPECT,
PET, EEG, and MEG.
◉ Magnetic Resonance Imaging (MRI). Answer: A neuroimaging
technique that uses magnetic fields and radio waves to produce
detailed images of the brain.
◉ Computed Tomography (CT). Answer: An imaging technique that
uses X-rays to create detailed cross-sectional images of the brain.
◉ Magnetic Resonance Spectroscopy (MRS). Answer: A non-invasive
imaging technique that provides information about the chemical
composition of tissues in the brain.
◉ Single Photon Emission Computed Tomography (SPECT). Answer:
A nuclear imaging technique that provides images of blood flow and
activity in the brain.
, ◉ Proton Emission Tomography (PET). Answer: An imaging
technique that uses radioactive tracers to visualize metabolic
processes in the brain.
◉ Electroencephalography (EEG). Answer: A technique used to
record electrical activity of the brain through electrodes placed on
the scalp.
◉ Magnetoencephalography (MEG). Answer: A non-invasive imaging
technique that measures the magnetic fields produced by neuronal
activity in the brain.
◉ Cognitive Abilities. Answer: Mental capabilities such as learning,
reasoning, problem-solving, and planning.
◉ Emotions. Answer: Complex psychological states that involve
physiological responses, subjective experiences, and behavioral or
expressive responses.
◉ Behaviors. Answer: The actions or reactions of an individual in
response to external or internal stimuli.
◉ Dopamine. Answer: A neurotransmitter that plays a role in
reward, motivation, and motor control.
