Your brain can alter sensory information through processes like sensory adaptation and perception. Sensory adaptation occurs when receptors become less responsive to constant stimuli, leading to diminished awareness over time, such as not noticing the smell of a room after being in it for a while. Perception involves the brain interpreting sensory data based on context, past experiences, and expectations, which can lead to misinterpretations of stimuli, like seeing a face in random patterns.

What part of the brain is injured when you can't feel anything in your lower body?
When you can't feel anything in your lower body, it may indicate injury to the spinal cord, particularly in the regions that transmit sensory information from the lower body to the brain. Damage to the spinal cord, especially in the thoracic or lumbar regions, can disrupt nerve pathways responsible for sensation. Additionally, injury to the somatosensory cortex in the brain, which processes sensory information, could also contribute to this loss of feeling.
What process by which unchanging information from the senses of taste touch smell and vision is ignored by the sensory receptor cells themselves is called?
The process by which unchanging information from the senses of taste, touch, smell, and vision is ignored by the sensory receptor cells is called sensory adaptation. This phenomenon allows sensory receptors to become less responsive to constant stimuli over time, helping the brain focus on new or changing information that may be more relevant for survival. As a result, individuals can better detect important changes in their environment while filtering out redundant sensory input.
Why can't a person smell or taste after a brain injury and if they do they just smell and taste smoke or have a taste like metal?
Loss of smell and taste after a brain injury can occur due to damage to the olfactory nerves or brain regions responsible for processing sensory information. When a person experiences phantom smells of smoke or tastes of metal, it may be due to misfiring neurons in the brain sending incorrect signals. This can lead to distortions in how the brain interprets sensory information, creating the perception of certain smells or tastes.
What is the order of a nerve path way?
The order of a nerve pathway typically follows this sequence: sensory receptors detect a stimulus and send signals to sensory neurons, which transmit the information to the spinal cord or brain. From there, interneurons process the information and may relay it to motor neurons, which then carry signals to effectors such as muscles or glands to elicit a response. This sequence allows for the integration of sensory input and the coordination of appropriate motor output.
How does sensory system affects behavior?
The sensory system plays a key role in influencing behavior as it processes external stimuli and relays information to the brain. Sensory input can impact emotions, decision-making, and responses to the environment. For example, a loud noise may trigger a fight-or-flight response, while a pleasant smell can induce feelings of relaxation or comfort.
What is a sensory neurones?
A sensory neuron is one that brings information about environmental simuli to the brain. It may also be called an afferent neuron.
What does your brain think you look like?
Your brain creates a mental image of what you look like based on sensory information and memories. This image may not always match your actual appearance, as it can be influenced by emotions and past experiences.

What is perceptious?
It seems like there may be a typo. Perhaps you mean "perception," which refers to the way our brain organizes and interprets sensory information from our environment. It influences how we understand and make sense of the world around us.

What is the primary function of nervous tissue?
To relay sensory information to the brain for interpretation and motor information to the muscles for voluntary or involuntary control. Nervous tissue also fulfills many other roles, like innervating organs that may release hormones.

What is the parential lobe?
There is no brain structure called the "parential lobe." It is possible that you may be referring to the parietal lobe, which is a region of the brain involved in processing sensory information, spatial reasoning, and some aspects of language. If you meant something else, please provide more context for clarification.
How does sensation travel through the central nervous system?
Sensation travels through the central nervous system via sensory neurons, which transmit signals from sensory receptors to the spinal cord and brain. Once these signals reach the spinal cord, they may be relayed directly to the brain or processed locally to facilitate reflex actions. The brain then interprets these signals, allowing us to perceive sensations such as touch, pain, and temperature. This process involves various neural pathways and regions, including the thalamus and cerebral cortex, which play key roles in processing and interpreting sensory information.
What happens when dorsal root is damaged?
Damage to the dorsal root can cause sensory deficits, such as numbness, tingling, or loss of sensation in the corresponding dermatome. This may affect the transmission of sensory information from the peripheral nerves to the spinal cord and brain. Additionally, reflexes may be impaired as a result of the disruption in the sensory input to the spinal cord.
