Cephalopods, such as octopuses and squids, are invertebrates that possess cerebral ganglia organized into a brain. This complex nervous system allows them to exhibit advanced behaviors, problem-solving skills, and learning abilities. Additionally, some species of annelids, like certain polychaetes, also show a degree of brain-like structures in their ganglia, though they are less complex than those found in cephalopods.

What structures are known as a simple brain in invertebrates?

Where is the basal ganglia located?
The basal ganglia is located deep within the brain, near the thalamus. It is nestled at the base of the cerebral cortex and is made up of several structures that are crucial for motor control, cognition, and emotion regulation.
What other animals have no brain?
Some lower invertebrates have what is called a ganglia, which is basically a poorly developed brain, but many lower invertebrates have no brain, and just connections of nerves throughout the body, which is called a nerve net.
Does the cerebral and basal ganglia is same?
Not really. Basal ganglia are a grouping of nerve cell bodies that are associated with various parts of the brain, mostly for sensory input, and one of these associations is the cerbrum.
What is the difference between a brain and a cerebral ganglion?
The term cerebral ganglion is reserved for invertebrate, while the term brain gaglion is used in reference to those with vertebrae. The ganglion refers to a cluster of nerves cells located in the peripheral nervous system.
Where is the Brian of an earthworm?
The earthworm doesn't have a brain per see, but its nervous system features a brain like pair of cerebral ganglia which is located above and in front of the pharynx.
Where are the cell bodies of cerebral neurons housed?
the cerebral neurons are housed in the cerebrums outer region called the CEREBRAL CORTEX
How many cerebral ganglia are there?
This is a trick question there are none!! Anyone who says differently is mistaken, definitively. A ganglia is defined as a collection of nerve cell bodies in the Peripheral Nervous system, within the Central nervous system (including the Cerebrum) they are called Nuclei.
What is the site of action in the brain where antipsychotics work?
Thes are the sites of action in the brain where antipsychotics work. The Basal ganglia, areas of the limbic system, the chemoreceptor trigger zone ,and the cerebral cortex
What area of the brain is affected in cerebral palsy?
The area of the brain that is affected by cerebral palsy is the cerebrum, it involves connections between the cortex and the cerebelum. This disorder usually starts at an early age or at the time of birth.
