The main objective of this course is to provide a solid grounding in the cellular and molecular mechanisms involved in the synaptic transmission.
It is expected that by the end of the course students are able to: i) understand the functional organization of central and peripheral nervous system; ii) characterize structurally and functionally neurons and glial cells; iii) explain the mechanisms involved in an active synapse, and also how we can pharmacologically modulate its activity; iv) develop basic laboratory skills in the area of cellular and molecular neuroscience.
Finally, it is expected that students will develop skills in searching, understanding, and discussing the scientific literature in this field.

Scientific papers (available in the moodle page)
Lectures will be based on textbook material and selected papers from the current literature.
Practical lessons include experiments, and analysis and discussion of the results.
I) Frequency of Neurobiology 22-23
1.To obtain frequency to the discipline it is necessary to participate in 2/3 of the P/TP classes
2. Participation in TP / P classes is recorded on attendance sheets and / or by the registration of participants in zoom meetings
3. Absences on evaluation days do not imply carrying out the evaluation on another day
4. Medical certificates or other justification of absences will only be accepted up to one week after the last day of the absence
5. The working groups (G 1 - G 8) must be formed by students, from the Lab A shift +Lab B shift +. During the P classes, the students work individually or in group
6. Delays of more than 20 min in a Lab class prevent the student from attending that class
The final classification of the discipline 0-20 val) results from the sum of the classifications obtained in 4 components
1. Component of theoretical / practical evaluation: 2 tests or exam - 60% of the final classification, 12 val. Minimum grade 50% of the classification in the average of the 2 tests or in the exam for passing.
Tests to be scheduled at the CLIP
Final grade of this component results from the average of the 2 tests rounded up to the tenth
2. Practical assessment component: Questionnaire to answer in a group regarding data from the first P classes (CNS anatomy and SN cells) - 2 val To be uploaded in moodle (22.9.2022).
3. Practical evaluation component: Research work on neuron glia interaction and oral presentation of the work - 1 val. Delivery of written work uploaded in moodle and oral presentation (max 5 min) (29.9.2022)
4. Project evaluation component: Written work in group in the form of a mini-article with the results obtained in classes P relating to WB for glial cells in different brain regions - 5 val. To be delivered until 16.12.2022, 23:59 m
The Exame de Recuros will be on a date to be set in the CLIP
The improvement of the grade of the theoretical/practical assessment component (tests; max 12 val) can be performed by means of a Exame de Recurso.
For approval, the tests/Exame de Recurso grade must be 50% of the final grade and the sum of the grades of the 4 components must be equal to or greater than 9.5 val
1. Organization of the nervous system: Central and peripheral nervous system.
2. Characterization of neurons and glial cells and neuron-glia interaction.
3. Chemical and electric synapses.
4. The electric impulse and the action potential.
5. Axonal Transport
7. Definition of neurotransmitter. Classical neurotransmitters (Acetylcholine, excitatory and inhibitory aminoacids, catecholamines, serotonin) and neuropeptides: biossynthesis, metabolism, effects on post-synaptic cell and general physiologic effects.
8. Pharmacological modulation of synapses; potential therapeutic targets.
9. Effect of drugs of abuse and others in specific synapses.
10. Molecular mechanisms of memory and learning in invertebrates.
11. Sensory systems: Sensation of touch.
