An Introduction to Learning and Memory

2023
Learning is the process of acquiring new information and memory is the retention or storage of that information. Different types of learning, such as non-associative and associative learning, and different types of memory, such as long-term and short-term memory, have been associated with human behaviors. Studying these components in detail helps behavioral scientists understand the neural mechanisms behind these two complex phenomena. JoVE's overview on learning and memory introduces common...

The video demonstrates the differentiation of neural stem cells (NSCs) using a microfluidic device comprising a somatic and an axonal compartment separated by a microgroove barrier. NSCs are introduced into the somatic compartment and are allowed to adhere. The NSCs differentiate into neurons inside the somatic compartment and extend axons through the microgroove barrier to the axonal compartment.

The Real-World What-Where-When memory test is a novel episodic memory test, in which participants need to recall which objects have been hidden in which locations on which of two distinct occasions. It is easy to run and is sensitive to normal cognitive aging.
FAQs
Electrical stimulation changes synaptic strength in a biological system or conductance in an engineered device. When those changes remain after the initiating signal, the system retains information as a cellular or electronic state. Subsequent activity can further modify that state, providing a mechanism for both memory persistence and updating rather than simple one-time signal transmission.
The pattern of electrical activity determines how information is represented in the system. Different stimulation patterns can produce corresponding changes in synaptic strength or device conductance, creating distinct internal states. This relationship allows the device to encode more than the presence of a signal, while continued activity can modify previously stored information.
Biological systems retain information through changes in synaptic strength, whereas engineered systems express comparable changes through electronic conductance. The physical substrates differ, but both approaches connect activity with a lasting internal state. This comparison lets researchers relate cellular memory mechanisms to device behavior without treating electronic storage as identical to neuronal signaling.
Synaptic plasticity links neuronal activity with changes that can persist and be modified. That connection provides a biological framework for examining how signaling relates to learning and memory. A neuronal memory device therefore serves not only as a storage concept but also as a way to investigate how activity-dependent changes may support information retention in neural systems.
A basic investigation applies defined patterns of electrical stimulation and examines whether they change synaptic strength or device conductance. Researchers can then consider whether the resulting cellular or electronic state persists and whether later activity modifies it. This workflow connects the input pattern with storage behavior and reveals how the system handles retention and updating.
Retention is indicated when stimulation produces a cellular or electronic state that remains after the initiating activity, rather than disappearing immediately with the signal. Modifiability provides a second outcome: later activity should be able to alter that state. Together, persistence and change distinguish memory-like behavior from simple signal passage.
In biology, these systems help researchers investigate mechanisms connecting neuronal signaling, synaptic change, learning, and memory. In engineering, they support neuromorphic computing and brain-inspired information processing. Their value comes from combining information retention with adaptability, an approach intended to improve how computing systems process changing patterns of information.
