Respuesta :
Researchers can examine the biological basis of fear, smell, memory, and diseases by using the following techniques:
1. The Role of Pro-inflammatory Cytokines in Memory Processes and Neural Plasticity.
2. Memory Systems.
3. The Memory Network.
4. Psychological and Neural Aspects.
Answer:
The correct answer is - optogenetics.
Explanation:
Optogenetics is a technique that is used in examining the basis of smell, fear, and memory that involves the use of light to regulate cells in a biological tissue especially neurons, which are genetically altered to show light ion channels.
Channelrhodopsin-2 is the most commonly used ion channel for triggering the optogenetics. When a definite number of positive ions have to get through the cell membrane, it causes the neuron to fire reaching the threshold.
Thus, the correct answer is - optogenetics.
