Neurotransmitters

Mind Map: Neurotransmitters

Central Idea

• Neurotransmitters

Main Branches

1. Definition

• Chemical messengers

• Transmit signals across synapses

• Essential for communication in the nervous system

2. Types of Neurotransmitters

• Excitatory

  • Glutamate

  • Acetylcholine

• Inhibitory

  • GABA (Gamma-Aminobutyric Acid)

  • Glycine

• Modulatory

  • Dopamine

  • Serotonin

  • Norepinephrine

3. Functions

• Mood Regulation

  • Serotonin: mood, anxiety

  • Dopamine: pleasure, reward

• Cognitive Functions

  • Acetylcholine: memory, learning

  • Glutamate: synaptic plasticity

• Motor Control

  • Dopamine: movement coordination

  • Acetylcholine: muscle activation

4. Disorders Related to Neurotransmitters

• Depression

  • Low serotonin levels

• Anxiety Disorders

  • Imbalances in GABA and serotonin

• Parkinson's Disease

  • Dopamine deficiency

• Schizophrenia

  • Dysregulation of dopamine

5. Receptors

• Types of Receptors

  • Ionotropic: fast response

  • Metabotropic: slow response

• Receptor Subtypes

  • NMDA (for glutamate)

  • D1, D2 (for dopamine)

6. Drug Interactions

• Agonists

  • Enhance neurotransmitter action (e.g., SSRIs for serotonin)

• Antagonists

  • Block neurotransmitter action (e.g., antipsychotics for dopamine)

• Reuptake Inhibitors

  • Prevent reabsorption (e.g., cocaine for dopamine)

7. Research and Future Directions

• Neuropharmacology

  • Study of drug effects on neurotransmitter systems

• Neurogenetics

  • Genetic influences on neurotransmitter function

• Therapeutic Innovations

  • Targeted treatments for mental health disorders
