Question

Long-term memory is possible because of the: strengthened pathways in the brain achieved through repeated signals sent across synapses. brain tissue that directly connects all neurons to each other. rich variety of pathways in the brain. individual pathways created each time a signal is sent from the same neuron to another neuron.

Answer 1

Strengthened pathways in the brain achieved through repeated signals sent across synapses.

Step-by-step explanation:

When we experience the world, our senses (sight, sound, taste, touch, smell) our organs (eyes, ears, tongue, skin, nose) send signals in the form of nerve impulses to our brain where it is stored as a memory.

Everything we experience is interpreted differently (eg. seeing a tree is different from tasting chocolate) and as the memory is reinforced (like seeing something every day), it becomes part of our long-term memory due to the repeated nerve impulse sent to the brain.
