梅尔文·A·古代尔:一个视觉神经科学家在行动

Neurons, the fundamental units of the brain and nervous system, function as the primary transmitters of information throughout the body. Their ability to communicate through electrical and chemical signals is vital for every bodily function, from regulating the heartbeat to processing complex thoughts. Each neuron has three main components: the cell body (soma), dendrites, and an axon, each specialized to facilitate swift and efficient neural communication.

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...

The cognitive neuroscience approach to development focuses on how the central nervous system supports emerging cognitive abilities. Neuroimaging and behavioral studies link specific neural systems to memory and cognitive processing in infancy.Distinct Memory Systems in the Developing BrainInfant long-term memory includes two distinct systems: implicit and explicit memory. Implicit, or nondeclarative, memory involves unconscious recall of skills and routines. It develops early and appears in...
