Neural basis of imprinting behavior in chicks
Newly hatched chicks memorize the characteristics of the first moving object they encounter, and subsequently show a preference for it. This “imprinting” behavior is an example of infant learning andExpand

Activation of cholecystokinin neurons in the dorsal pallium of the telencephalon is indispensable for the acquisition of chick imprinting behavior
Chick imprinting behavior is a good model for the study of learning and memory. Imprinting object is recognized and processed in the visual wulst, and the memory is stored in the intermediate medialExpand

Demonstration of a Neural Circuit Critical for Imprinting Behavior in Chicks
Imprinting behavior in birds is elicited by visual and/or auditory cues. It has been demonstrated previously that visual cues are recognized and processed in the visual Wulst (VW), and imprintingExpand

Spontaneous depolarization wave in the mouse embryo: origin and large‐scale propagation over the CNS identified with voltage‐sensitive dye imaging
Spontaneous embryonic movements, called embryonic motility, are produced by correlated spontaneous activity in the cranial and spinal nerves, which is driven by brainstem and spinal networks. UsingExpand

Pharmacological mechanisms underlying switching from the large‐scale depolarization wave to segregated activity in the mouse central nervous system
During the early development of the nervous system, synchronized activity is observed in a variety of structures, and is considered to play a fundamental role in neural development. One of the mostExpand

Functional development of the vagal and glossopharyngeal nerve-related nuclei in the embryonic rat brainstem: optical mapping with a voltage-sensitive dye
We investigated functional organization of the vagus nerve (N. X)- and glossopharyngeal nerve (N. IX)-related nuclei in the embryonic rat brainstem and compared their development and spatialExpand

Optical survey of vagus nerve-related neuronal circuits in the embryonic rat brainstem
The multiple-site optical recording technique with a voltage-sensitive dye, NK2761, was used to survey the functional organization of neuronal networks related to the vagus nerve (N.X) in theExpand

Elevated expression of brain‐derived neurotrophic factor facilitates visual imprinting in chicks
With the aim of elucidating the neural mechanisms of early learning, we studied the role of brain‐derived neurotrophic factor (BDNF) in visual imprinting in birds. The telencephalic neural circuitExpand

Positive feedback of NR2B‐containing NMDA receptor activity is the initial step toward visual imprinting: a model for juvenile learning
Imprinting in chicks is a good model for elucidating the processes underlying neural plasticity changes during juvenile learning. We recently reported that neural activation of a telencephalicExpand

Characteristic expressions of the natriuretic peptide family in the telencephalon of juvenile chick
Elucidation of the genes regulating the critical (sensitive) period of imprinting behavior may shed light on the mechanism underlying neural plasticity in early childhood learning. We focused on theExpand
