How do cells respond to different stimuli
WebThey discovered three different types of neurons that can be distinguished based on how they respond to visual stimuli that they called: simple cells, complex cells, and hypercomplex cells. V1 neurons transform information (unlike LGN cells whose receptive fields look just like those of ganglion cells) so that they are orientation selective and ...

WebLiving organisms have some senses (sight, smell, touch, taste, etc.) that can help them to detect changes in their external environment, as well as their internal balance and respond to them. Some organisms (such as herbivores) respond to stimuli much quicker than others (such as plants). Homeostasis WebApr 1, 2024 · Physical stimuli are essential for the function of eukaryotic cells, and changes in physical signals are important elements in normal tissue development as well as in disease initiation and progression. The complexity of physical stimuli and the cellular signals they initiate are as complex as those triggered by chemical signals.
WebJun 8, 2024 · All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life. Figure 1.7. 1: Multicellular Organisms: A toad … WebCells respond to stimuli using organ effectors.
