Signals and perception: the science of the senses

This sensory neuroscience module uses fundamental concepts from biology, chemistry, physics and psychology to explain how we interact with our environment through the senses and is therefore an opportunity for you to study an interdisciplinary topic. For each of the senses, you’ll investigate how sensation begins with a stimulus that is converted into an electrical impulse; how that is transmitted to the brain; and how the brain combines these messages – to arrive at a ‘perception of the stimulus’. The module is designed to be accessible to students pursuing a wide variety of degree studies.

What you will study

The module explores the ways in which exciting ideas and findings at the forefront of biochemistry, biophysics and molecular biology have transformed our understanding of how we experience the world through our senses. It provides an understanding of:

  • the nature of the communication signals (e.g. light for vision, sound for hearing, molecules for taste and smell)
  • primary transduction mechanisms that convert signals into electrical impulses
  • the common nature of the transmission and processing of the resulting electrical signal within the nervous system
  • sensory disorders and treatments.

The material is divided into six blocks, presented in three printed books, beginning with two blocks introducing the senses and the nervous system. These blocks are designed to give you sufficient neuroscience background to work through the remainder of the module and include online activities to maximise your understanding of this essential information. Blocks 3-6 also include online activities, as well as additional resources which can be accessed online.

Throughout the module the emphasis is on the commonalities and integration between the sensory systems, as you examine the processes from sensation to perception for each sense as well as the impact and treatment of impairment or loss of sensory systems.

Block 1 Introduction to the senses. This block introduces you to the human senses, concentrating on observations and experiences that raise questions about how the senses work.

Block 2 Introduction to the nervous system. In this introduction to neuroscience, and in particular to the neuron, you’ll look at the way electrical impulses created by external signals of whatever kind are transmitted throughout the nervous system; and where they are processed and give rise to our personal picture of the world. You’ll also explore the techniques that are commonly used in investigating the senses.

Block 3 Somatosensation describes the somatic sensory system including how we sense and perceive touch, pain and our own body position and movement. The latter is often considered a hidden sense and in this block you will explore the impact of its loss. You will also cover the multidisciplinary treatment of pain.

Block 4 Hearing and balance. In this block you’ll explore the nature and properties of sound waves; the specialised anatomy and functioning of the ear; and how auditory perception arises, including for speech and music. This block also focuses on the vestibular system, which is housed within the ear, and how this system gives rise to our sense of balance.

Block 5 Vision. This block is exclusively dedicated to how we sense and perceive visual information. It is the longest block, in part because the most is known about vision but also because vision is in many ways the most complex of the senses. In this block you’ll cover the nature and properties of light; the optical system of the eye; processing of visual information within the brain; and how we perceive different elements of the visual scene such as colour.

Block 6 The Chemical Senses. The related senses of smell and taste as well as the sense of flavour are the focus of this block. The topics covered include the molecular characteristics of substances that we smell or taste; the nature of the receptors involved; the coding of smell and taste and how smell may be used in diagnostics.

Teaching and assessment

Support from your tutor

Throughout your module studies, you’ll get help and support from your assigned module tutor. They’ll help you by:

  • Marking your assignments (TMAs) and providing detailed feedback for you to improve.
  • Guiding you to additional learning resources.
  • Providing individual guidance, whether that’s for general study skills or specific module content.
  • Facilitating online discussions between your fellow students, in the dedicated module and tutor group forums.

Module tutors also run online tutorials throughout the module. Where possible, recordings of online tutorials will be made available to students. While these tutorials won’t be compulsory for you to complete the module, you’re strongly encouraged to take part.

Assessment

The assessment details for this module can be found in the facts box.

Future availability

Signals and perception: the science of the senses (SD329) starts once a year – in October.

Regulations

As a student of The Open University, you should be aware of the content of the academic regulations which are available on our Student Policies and Regulations website.

    Course work includes:

    3 Tutor-marked assignments (TMAs)
    2 Interactive computer-marked assignments (iCMAs)
    End-of-module assessment
    No residential school


    Entry requirements

    The module should appeal to students from many backgrounds, and will be of particular interest if you enjoy interdisciplinary study. It is suitable if you are specialising in biology, chemistry, physics or psychology, or following a degree in health sciences.

    This is an OU level 3 module. OU level 3 modules build on study skills and subject knowledge acquired from studies at OU levels 1 and 2. They are intended only for students who have recent experience of higher education in a related subject, preferably with The Open University.

    If you are working towards our BSc (Honours) Health Sciences, you should have completed your OU level 1 and OU level 2 study before starting this module and we recommend that you study Brain, mind and mental health (SK298) as part of your optional OU level 2 study.

    It is essential that you establish whether or not your background and experience give you a sound basis on which to tackle the module, since students who are appropriately prepared have the best chance of completing their studies successfully. The Science Faculty has produced a booklet Are You Ready For SD329? to help you to decide whether you already have the recommended background knowledge or experience to start the module or whether you need a little extra preparation.

    If you have any doubt about the suitability of the module, please speak to an adviser.

    Ways to pay for this module

    Open University Student Budget Account

    The Open University Student Budget Accounts Ltd (OUSBA) offers a convenient 'pay as you go' option to pay your OU fees, which is a secure, quick and easy way to pay. Please note that The Open University works exclusively with OUSBA and is not able to offer you credit facilities from any other provider. All credit is subject to status and proof that you can afford the repayments.

    You pay the OU through OUSBA in one of the following ways:

    • Register now, pay later – OUSBA pays your module fee direct to the OU. You then repay OUSBA interest-free and in full just before your module starts. 0% APR representative. This option could give you the extra time you may need to secure the funding to repay OUSBA.
    • Pay by instalments – OUSBA calculates your monthly fee and number of instalments based on the cost of the module you are studying. APR 5.1% representative.

    Joint loan applications

    If you feel you would be unable to obtain an OUSBA loan on your own due to credit history or affordability issues, OUSBA offers the option to apply for a joint loan application with a third party. For example, your husband, wife, partner, parent, sibling or friend. In such cases, OUSBA will be required to carry out additional affordability checks separately and/or collectively for both joint applicants who will be jointly and severally liable for loan repayments.

    As additional affordability checks are required when processing joint loan applications, unfortunately, an instant decision cannot be given. On average the processing time for a joint loan application is five working days from receipt of the required documentation.
