What is a receptive cell?
The receptive field encompasses the sensory receptors that feed into sensory neurons and thus includes specific receptors on a neuron as well as collectives of receptors that are capable of activating a neuron via synaptic connections.
What does receptive field mean?
The receptive field, or sensory space, is a delimited medium where some physiological stimuli can evoke a sensory neuronal response in specific organisms.
What are the two receptive fields?
Receptive field subregions: The area within the receptive field is subdivided into two regions, center and surround.
What is retinal field?

What do amacrine cells connect to?
Amacrine cells (named by Cajal for their lack of an axon) lie in the inner retina and make connections with bipolar cells and ganglion cells. They exist in a wide variety of morphological types (Masland, 1988; Wässle and Boycott, 1991). With rare exceptions, little is known about their roles.
Are rods and cones photoreceptors?
The two classic photoreceptor cells are rods and cones, each contributing information used by the visual system to form a representation of the visual world, sight.
What is receptive field eye?
RECEPTIVE FIELDS, FROM THE RETINA TO THE CORTEX. Each of the neurons in the various layers of the retina “covers” an area in your field of vision. This area in space where the presence of an appropriate stimulus will modify the activity of this neuron is called the receptive field of this neuron.
How do receptive fields work?
To put it another way, a receptive field is the receptor area which when stimulated results in a response of a particular sensory neuron.
What neurotransmitter do amacrine cells use?
| Amacrine cell | |
|---|---|
| Function | inhibitory or neuromodulatory interneurons |
| Neurotransmitter | gamma-Aminobutyric acid, glycine, DA, or 5-HT |
| Presynaptic connections | Bipolar cells |
| Postsynaptic connections | Bipolar cells and Ganglion cells |
