🧠 EPSP (Excitatory Postsynaptic Potential)
پتانسیل پس‌سیناپسی تحریکی

A temporary change in the postsynaptic neuron’s membrane potential that moves toward depolarization (becoming less negative), increasing the neuron’s likelihood of firing. This is typically caused by excitatory neurotransmitters like glutamate.

A temporary change in the postsynaptic neuron’s membrane potential that moves toward hyperpolarization (becoming more negative), decreasing the neuron’s likelihood of firing. This effect is usually caused by inhibitory neurotransmitters like GABA.

A crucial protein involved in neuronal growth, survival, and plasticity. BDNF plays a role in learning, memory, and neuroplasticity, and its deficiency has been linked to neuropsychiatric disorders such as depression and Alzheimer’s disease

A virtual representation of the human body in the sensory or motor cortex, showing how much cortical space is dedicated to each body part. The sensory homunculus exaggerates body parts with higher sensitivity (e.g., hands, lips), while the motor homunculus highlights areas requiring finer motor control

The inability to recall events or information encoded before a brain injury (e.g., head trauma, stroke, or surgery). This type of amnesia typically affects memories closer to the time of injury, while older memories (e.g., childhood) may remain intact.

🧠 IPSP (Inhibitory Postsynaptic Potential)
پتانسیل پس‌سیناپسی مهاری

🧠 BDNF (Brain-Derived Neurotrophic Factor)
فاکتور نوروتروفیک مشتق از مغز

A crucial protein involved in neuronal growth, survival, and plasticity. BDNF plays a role in learning, memory, and neuroplasticity, and its deficiency has been linked to neuropsychiatric disorders such as depression and Alzheimer’s disease

🧠 Homunculus
هومونکولوس

A virtual representation of the human body in the sensory or motor cortex, showing how much cortical space is dedicated to each body part. The sensory homunculus exaggerates body parts with higher sensitivity (e.g., hands, lips), while the motor homunculus highlights areas requiring finer motor control

🧠 Retrograde Amnesia
فراموشی پس‌گستر

The inability to recall events or information encoded before a brain injury (e.g., head trauma, stroke, or surgery). This type of amnesia typically affects memories closer to the time of injury, while older memories (e.g., childhood) may remain intact.
