概括

八胺和多巴胺在Bactrocera dorsalis的关联学习中起着不同的作用. 多巴胺对厌恶性学习至关重要,而八胺对食欲性记忆检索至关重要.

科学领域:

神经科学是一个神经科学.
动物行为动物行为
昆虫生理学昆虫生理学

背景情况:

多巴胺 (DA) 在关联性学习和记忆中的作用是公认的,特别是在厌恶性调节中.
最近的研究表明,多巴胺除了在各种物种中产生厌恶条件之外,还具有更广泛的功能.
东方果 (Bactrocera dorsalis) 作为一个模型生物来研究神经递质在关联性可塑性中的作用.

研究的目的:

Physiology of Smell and Olfactory Pathway

Physiology of Smell and Olfactory Pathway

Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
The olfactory...

Olfaction

Olfaction

The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Olfactory Receptors: Location and Structure

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
