Synaptic Signaling01:09

Synaptic Signaling

Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.
The presynaptic neuron fires an action potential that...
Signal Sequences and Sorting Receptors01:41

Signal Sequences and Sorting Receptors

Signal sequences are short amino acid sequences that guide newly synthesized proteins to their proper location within the cell. Classical signal sequences are fifteen to sixty amino acids long and present at the N-terminus of a polypeptide chain. Each signal sequence has a conserved segment of basic residues towards their N terminus, a hydrophobic core, and a C-terminus rich in polar residues. The C-terminus also contains a signal cleavage site and features a -3 -1 sequence motif. The -3-1...
Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

Role of Hippocampus in Memory01:19

Role of Hippocampus in Memory

The hippocampus, a critical brain structure, plays an essential role in memory processing, particularly in the formation and retrieval of memory. This small, seahorse-shaped region is located within the medial temporal lobe, with one hippocampus in each brain hemisphere. Experimental studies involving lesions in the hippocampi of rats have demonstrated significant impairments in tasks such as object recognition and maze navigation, indicating the hippocampus involvement in both recognition and...

Background:

  • The precise function of the human hippocampus remains debated among neuroscientists.
  • Theoretical models often conceptualize the hippocampus as a computational device.
  • Recent findings suggest the hippocampus's role extends beyond declarative memory.

Purpose of the Study:

  • To introduce a novel strategy for investigating information processing within the human hippocampus.
  • To link theoretical perspectives with empirical data on hippocampal function.

Main Methods:

  • Utilizing functional magnetic resonance imaging (fMRI) to measure brain activity.
  • Focusing on neural responses to novelty as an indicator of hippocampal function.

Main Results:

  • Novelty responses detected via fMRI offer insights into the neural representations and computations of the hippocampus.
  • This approach provides a method to study hippocampal information processing in humans.

Conclusions:

  • A focus on the information processing aspects of the human hippocampus can bridge theoretical and empirical research.
